Thank you for the detailed reply Ben.
I am really intrigued by these paper models.
Back in the late 1980s/early 1990s, I built three different large Lionel O Gauge layouts and I built a number of model kits for the layouts. When we moved in 1993, I lost the available space for my then current layout. I have subsequently sold off or traded most of my Lionel Trains.
I did a lot of weathering of the buildings with an airbrush at the time, but I haven’t picked up the airbrush in many years. The motor for it is now rigged up on my test bench which I use to test engines undergoing restoration/repair.
Keep us up to date on your model building please.
