Key Imports Brass NYC. Fantastic offering and they look new to me. The units look great on my photo table and are the 1940 version (they made a few different ones). I noticed there are not enough couplers for the four cars, but everything that is included is pictured. The boxes look nice, but the white bases do have some brown age spots as pictured. Please review the pictures. The W15 in the listing title refers to my inventory location. Let me know if you have any questions.
