Hi,
After picking up a 150 engine and several passenger cars for it, I have started to look at the freight cars that also ran with the 150 engine. I have seen the 901 caboose and 800 box car that have the matching couplers. On the bay I saw a 804 tank car that has the simple drop in type couplers without the journal boxes, but when I look at the photos from O'Brien's book that all seem to have the latch style coupler. The openings on the frame appear the same. So my question is, did Lionel use the simpler style couples in the 1920's and then switch over to the latch style in the 1930's?
Thank you,
Kevin Coyle
