Bruce, there were 300 each of F-50-10s (built in 1939) and F-50-11s
(built in 1941), but there were also 300 F-50-9s (built in 1930) that
were identical to the F-50-10s except for their trucks.

The UP owned many Harriman Standard 40'10" flat cars, as did the
Southern Pacific.  This is another flat car model that's much needed
but currently unavailable. 

Thanks Richard!

I did some looking in the 1943 ORER and found the following:
1943 ORER entries for Union Pacific Flat cars
length number reporting marks
36' 4" 20 OWR&N
39' 25 UP
39' 68 OSL
40' 8" 118 OWR&N
40' 10" 2140 (OWR&N-173, LA&SL-86, UP-1761, OSL-120)
52' 8" 298 UP F-50-9
300 UP F-50-10
53' 6" 300 UP F-50-11

Total: 3269

I don't know that all of those 40' 10" cars are identical, but that
sure seems to be the "major" UP fleet of WWII. As Jeff pointed out in
his Cocoa handout, the F-50-11 made up ~10% (in 1950, as well as 1943).
Basically, I should have a 6:2:1 ratio of 40'10" cars to F-50-9/-10 to
F-50-11. Scratchbuilding or resin sound like the only option... Have
these been done in brass?
