i began this project last spring around the beginning of the lockdown. Then set it aside for the summer and picked it up again a few months ago. It turned out to be the most challenging kit I have attempted to date. Most of the time spent on the frame starting with having to punch a few hundred rivets before the assembly. This wouldn't have been possible without my homemade resistance soldering tools though a lot was done with my little 45 watt pencil iron.
I modeled a restored 19000 class caboose located at our local museum in Industry, NY. It was just restored a few years ago and still supports fresh paint with little sign of weathering.
More Pictures of the prototype have been posted on the Real Trains forum.
This is what I started with. Credit Mullet River.
And here is where it is now, with just a few more details like poling pockets to be added.
