Presumably these are combines 10 and 11, both retired 8-1-37, then transfered to MOW 1-1-39, retired 7-28-43 and sold to US Gov. for use on WP&Y. The photos might be the same car, but in the first photo the car is not coupled on one end and in the other it is in between 2 cars. Do you have any further info on this Martin?
