Will be more available and be on here more
Wow, Jagrick, love these! Some are pristine. Are some of them reproductions? I dabbled in reproducing dealer displays in the 90s, including a D-133 (like the one you have). Also fancy train cabinets.
Right now I am making an o gauge pre-war table layout, very loosely based on the one in Tim Holland's book. Lionel catalogued a lot of "layouts" and "scenic railways" but I don't know how many were actually produced.
It's going to be a beauty. What are the tunnel portals? Homemade tin? My layout has paired bridges as well- the low ones. I'll dig out a photo.
