AMCDave posted:The body and frame are originally AHM Rivirossi castings. Lionel used these for the 40ft gondola with plastic coal load but I have not seen this box car body used by Lionel but could be. Or it could be like the 15 AHM box cars I own that I converted to 3r trucks and couplers.

This is not possible. Look at the pick in my post or the third pick in the o.p. post. The floor has a raised semi round area above the coupler shank. This was NOT the case with the original Ahm/Pola/Atlas boxcars and reefers of the 1970. Also the die cast truck is offset attached- NOT at the bolster as was o scale cars and the pola/ahm/atlas plastic cars the time were.
Those Lionel early (full) die cast trucks could not be attached to a full o scale bolster without obtaining the high water pants look!
