These are inserts for N scale wood gondola cars to make open-air excursion cars. One is for a 40 foot wood gondola that was deeper, the other is for a 42 foot wood gondola. I designed the top portion to fit in a 40' wood gondola that I had, not sure of brand, I bought it in a collection. Then I found 2 reasonably priced Bachmann 42' wood gondolas on EBay and adjusted the length and depth.
