I wanted a caboose that would fit my MDC cars better than the USA caboose I had picked up a few years back, it is of the wrong era. I found some old plans in a decal book and altered/changed them some to fit the size of the MDC cars, so I’m not sure of any scale, just going for the right ‘look’ to me. I used 1/8" plastic for the basic box. Frame/roof are some Delton pieces I got off ebay last year in a buy. LGB trucks in this shot, but I may just build my own.
I’m using my metal duct tape method on this also, since it is a metal caboose. Rivet counters have fun! I used a pounce wheel to emboss them from the back. Ballpoint pen from the front for the windows/door.
