According to the Kaiser-Frazer Operating Report for the 3 months ending March 31, 1950, Kaiser-Frazer built 980 Virginians during the 1949-50 model run, this included 1 Virginian built in Jasnuary 1950. As of 3/31/50, 874 of these were sold & only 2 were classed as new, undriven, unsold cars in inventory. This totals 875 new cars soid to dealers and distributors or available for sale. This leaves 115 finished cars.
Five cars were on the books as assigned to the Experimental Engineering department of Kaiser-Frazer, 45 were assigned to Kaiser-Frazer Sales Corporation for field uses (used by people in the various sales offices across the country), and another 45 were available as "executive driven" cars for resale through the By-Products Store (surplus materials/vehicles store at Willow Run). This announts for another 95 cars. Kaiser-Frazer Export Corporation still had one for its uses outside the 48 states. There were also a total of 8 cars assigned to other K-F departments at Willow Run or available for resale after use by the same other "executive driven" uses. This comes to 104 vehicles. Adding the two "legally new" cars in inventory comes to 106 vehicles.
The report also states (with no specific detail noted) that 1 Virginian was re-purchased from a terminated distributorship during the first quarter. That car plus the 105 other cars listed previously accounts for the difference between cars built and cars sold to dealers or distributors. In other words, every car built is accounted for. None were turned into 1951 Frazer Hardtops.
The 1951 Frazer Manhattan Hardtops were made from either body stampings run through body fabrication with different quarter panels and some other minor revisions or bodies built up butg not put on chassis in the body bank. It cost $$$ to "modify" the built up cars but it was cheaper than selling the material for scrap or building out more 1950 Virginians that would never be saleable without substantial price cuts.
