Features required wooden parts, instructions and full size plans. The model has not been started. Inventoried 100% complete with all parts and instructions. From Bill Baker Jr - "California Model Company originated in Long Beach, Calif in the late 1940's or early 1950's. My grandparents, William (Bill) Loyal Baker and his wife, Ruth (Tripp) Baker were the founders. The company started out as primarily balsa based model aircraft but later, in the late 50's or early 60's, branched into the model RR craft kits and Cub Scout craft kits. They even had a balsa speed boat kit powered by a model airplane gas engine adapted to fit. When they retired, around 1968 or 1969, they sold the business and the "shop" in North Long Beach they built to house their business. I have many fond memories as a young child "working" with them in the shop, assembling kits. I have a few unbuilt kits today!"

Wood Model Kit, Box Condition: Good+
$36

Comet Stinson - 6 Inch Wingspan Solid Wood Model Airplane, 1/68, S6

But there were a small but measurable percent that built solid aircraft display models of great detail. This required great skill worthy of the shipbuilders of old, especially considering the limited offerings. Many manufacturers, such as Comet issued blocks of wood and a plan - the famous (or infamous) 'Make Wood Look Like Plane' kits.
Comet Sento Ki-001 Japanese Navy Fighter Official Identification Kit, 1/72, IA-16
Wood Model Kit, Box Condition: Good-
$48
A very rare kit from about 1941/42. This model is 'Identical to the one used in the Model Building Program of the US Office of Education sponsored by the US Navy, Bureau of Aeronautics' which was a program launched in 1941. During WWII the higher speed of aircraft made the traditional WW1 'recognition cards' nearly useless and 3D models were needed. The US Armed Forces looked to the general population to produce recognition models. While not fully successful due to irregular quality and supply, it quickly paved the way for superior injection molded recognition models. This kit features wood blocks, sheets and stock, glue, sandpaper, an excellent, very thick paper template, outline & gauge sheet as well as fold-out full size plans with aircraft history and detailed carving and building instructions. Never started and complete. Although misidentified, the "Sento Ki-001" is a single-engine, low wing monoplane (that is not a Zero). The large right end flap on the box has fallen off and is inside the box. The left one, with the name of the kit, is present. The box is only 'good-'.
Maircraft Spad 13 - Solid Wood Model Airplane - (Spad XIII), 1/48, S19
Wood Model Kit, Box Condition: Good
$22
Maircraft was originally founded in the early or mid 1930s by Gordon Christoph and went by the name Aircraft Model Company. The company produced a typical line of solid 'profile cut' kits that required the usual high talent levels for carving and finishing. A former Comet Model Airplane & Supply Co. salesman, Jack Mair, bought the company in the early 1940s and renamed it Maircraft. This company was one of the handful of solid kit producers who issued models in a consistent 1/48 scale during the 1930s and 1940s (others included Hawk and Dyna-Model). This lead to one of the most desirable and rare model kits ever produced in the USA - the wood/plastic 1/48 United DC-3 model issued immediately after World War 2. Other than the P-61 and a few other Maircraft offerings, most were simple kits that sold for the low price of about 35 cents and gave the owners many hours of pleasurable work. This kit features a full size plan with instructions steps, fuselage that is factory cut to about 70% complete, profile cut wings and tail, fully formed wheels and clear material for the windshield. Never started. It has been inventoried complete with all parts and includes decals and instructions.

Drone Engineering Secret Weapon - Spectacular Diesel Flyer - 38 Inch Wingspan Super Stunt Control Line Model Designed For Diesel Engine
Wood Model Kit, Box Condition: Fair-
$125
Very rare and from 1948. This is a completely prefabricated, balsa and hardwood super-stunt control line design by Leon Shulman. At that time it was capable of doing every possible maneuver that control line models could perform and some that could not be done, such as a loop and vertical 8's. It can literally be built in a few hours and features factory cut and carved, high-quality wooden parts, shaped and hollowed leading edges, tapered training edges, hardware, fully formed wire landing gear (or to be used as a take-off trolley that remained on the runway to improve performance), covering tissue and more. The full size plans include heavily illustrated step-by-step assembly as well as complete flying tips from the famous designer. NOTE: this kit has 'excellent' quality sub assembly as follows: bellcrank to elevator; upper & lower fuselage and hardwood reinforcements assembled. Horizontal stabilizer and elevator are very neatly sanded. There is no other assembly. The model has been inventoried 100% complete with all parts and paperwork included. Please note that the covering tissue has bug damage. In 1948 Drone Diesel also produced and marketed the 'Dronette' Sport Flyer & Stunt Trainer and the 'Hot-Rock,' a National Open Stunt Champion in 1947. These model, with the 'Secret Weapon,' promoted 'Diesel At Its Best,' the Drone Diesel Engine with a Class B displacement of .297, bore of 21/32 and Stroke of 7/8". The compression ratio was whopping 18 to 1. A speed control and variable compression head were also available.
Cleveland 1931 Bayles Gee Bee Racer - Balsa Flying Model Airplane Kit, 1/16, SF-17
Wood Model Kit, Box Condition: Good++
$110
Very rare 1936 'Silver Box' issue. This is a Cleveland 'SF' or 'Scale Flying' model in museum scale of 1/16. This is the earlier simple cardboard box with the silver printing. All Cleveland kits were exceptionally complete and this one is no exception. Features very high quality balsa printwood, stringers and spars, fully carved nose, fully formed & finished wheels, thrust button, balsa blocks and stock as required, adhesive instrument panel, pre-hollowed wheel pants stock, metal stock, clear windshield celluloid and covering tissue. Includes the famous CD high-quality plans. Even includes the original factory packing tissue. The model has not been started. Inventoried complete with all parts and paperwork. The Cleveland Model and Supply Company played a pivotal role in the development of true scale models. In 1909 Bleriot's English Channel flight caused a surge in aviation and model aircraft around the globe. Several companies were ideally positioned to take advantage of the aviation craze. In the USA, Wading River Manufacturing Co. (1909), White Aeroplane (1911), Ideal Model Aeroplane (1911), Broadfield Model Aeroplanes (1919) were among these pioneers, offering everything from plans and parts to complete kits and ARF models. Lindbergh's 1927 crossing of the Atlantic Ocean caused an even bigger world-wide phenomenon called "The Aviation Craze" that extended up to the start of World War II. Many companies such as Megow, Guillow's and others started right around the time of Lindbergh's flight. Some of these models flew and flew well, but they all had one thing in common - were generally not accurate scale representations. In 1929, a youngster named Ed Packard had a very advanced dream- to produce incredibly accurate, true scale models that flew perfectly. This radical idea established the world's longest running single-owner (77 years) model airplane business- Cleveland Model and Supply Company. To this day, Cleveland models are treasured as the most accurate flying scale models produced. The fact that Mr. Packard started and successfully grew this business during The Great Depression is a testament to his ideals and business skill. I highly suggest the excellent book called 'Aviation's great Recruiter- Cleveland's Ed Packard' by H.L. (Herm) Schreiner. It is an excellent history of the man, his company and the times of the Golden Age of Model Aviation.
Cleveland Laird Solution 1930 Thompson Trophy Winner - 10.63 Inch Wingspan Free-Flight Rubber Powered Flying Aircraft, 1/24, D-46
Wood Model Kit, Box Condition: Fair+
$55
Very rare and from the mid 1930s to the early 1940s. This is a Cleveland 'D' or dwarf kit. The term 'Dwarf' is just a bit deceptive, as it is Cleveland's designation for 1/24 scale. Most Cleveland kits were designated 'SF' or Scale Flying - 1/16 scale. The Dwarf kits were needed to fill a market demand for smaller flying models. All Cleveland kits were exceptionally complete and Dwarfs were no exception, containing very high quality balsa printwood, stringers & spars, fully formed wheels, covering tissue, a wood propeller that is about 90% carved and just needs final sanding, gray rigging thread (if required), metal and balsa stock as required and more. With Cleveland's famous high-quality plans. While the box has significant wear, the kit inside is still 'factory tissue sealed.' When the Cleveland workers packed each kit, they wrapped them in tissue that effectively made a seal which has not been disturbed. Whoever buys it will be the first one to see the contents since it was packed in the factory over 90 years ago.

Eureka Hobby AD-2 Skyraider - 24 Inch Wingspan Class 1/2A Engine Control Line Flying Aircraft
Wood and Metal Model Kit, Box Condition: Good++
$275
Extremely rare, highly prefabricated kit from post-war Japan. Most likely from the early 1960s. These kits were produced to complete in the saturated American market, and they distinguished themselves by the quality and amount of work already done.

Never started and complete. Eureka Hobby made a large line of giant scale gas powered models; they were not inexpensive, which is what makes them very rare today. This Bearcat was $8 in the early 1960s. Other aircraft produced, along with the wingspans and price are as follows: F4U Corsair (31" $10), Me-109E (36" $8), FW-190 (36" $8 and 26" $5.95, AD-4 Skyraider (36" $8), AD-2 Skyraider (24.5" $4.95), L-17 Navion (33" $8), F-94C Starfire with an all metal body and wings for Tiger-Jet engine (31" and $19.95, DC-6B (73", 59" long, four tanks, aluminum cowls, shock absorbing gear, four props for $47.50 - I had one of these, it was an amazing kit), Super DC-3 (61" $29.95, Fairchild Packet Transport (56" $29.50), C-45 Twin Beech (45" $28), Military DC-3 or C-47 (48" $24.50), SA-16 Albatross (54" $25.95), P-2V4 Neptune (51" $21.50), Commando (62" $28), Mig-15 (all metal body and wing, designed for Tiger Jet engine, 36" $22.50), F-84E Thunderjet (37.5" for Dyna-Jet fully enclosed engine and has rear aluminum fuselage $22.50) and finally a B-29 - the line flagship.
