Here I am!
There were actually 42 1949-50 Kaiser Convertibles produced. There were actually 37 different exterior paint colors for 1949 and 62 interior fabrics offered in 1949, which includes different colors of the same cloth, leather or vinyl material. The number of cars built comes from the Kaiser-Frazer Corporation Operating Report dated 3/31/50 and a publication designed for sales people called FACTS, FACTS, FACTS. The company had planned to offer a broader range of colors for cars, but sales were rather dismal and a lot of cuts in the offering list were made...some were noted in Ordering Information but never actually went on vehicles.
What I would suggest is that you post or email me the numbers off the door post serial number tag and the body tag found on the firewall of the engine compartment. I can identify any factory installed equipment, original paint & upholstery, etc.
You may not be aware, but one of the convertibles built was exported to the then relatively new nation of Pakistian. It, along with 2 Frazer Manhattan convertibles were used as official state vehicles for parades, VIP transport, etc.
The 1949-50 designation reflects the fact that any new, undriven, untitled cars in factory, distributor or dealer inventories on November 4, 1949 were re-tagged (DOOR POST) as 1950 model year products. The "1950 model year" lasted until March 15, 1950, when the 1951 model year began.
