The wig wag signal is a Wiseman Model Services kit. It unfortunately does not operate. I built the signal so it will rotate when moved manually with the very slim hope that someday I will add a mechanism to make it work.
The first (which is also the last) visible backdrop to the left plus the only one visible to the right are Backdrop Warehouse rejects. In their early years, they were still figuring out the printing details and would sell the rejects at a significant discount. The occasional lone builds are Clever Models paper buildings. The rest of the backdrops are Sceniking. They went out of business a few years ago (I think the owner wanted to retire). Their website has been updated recently so it looks like they are back in business.
