I recently "discovered" AMT Aluminum passenger cars and I must say I am completely fascinated by them! VERY interesting construction, very high quality, and they look wonderful. They were apparently made mostly with Santa FE and New York Central road names.
I have been working on several cars and find they come with 2 types of coupler. One is a fixed plastic coupler and the other is a cast metal operating coupler. They are both compatible with each other as well as Lionel and MTH. I have also found that they can be polished up to look really nice. They come in both smooth roofs and ribbed roofs. The smooth roofs polish up to a mirror shine.
The observation car has what initially appeared to be a plastic disc as a drumhead. When I illuminated it with a flashlight I was amazed at the design! The regular car light are not enough to light up the drumhead so I added a lamp.
I am wondering if anyone knows of a source for parts for these cars. Specifically I need a few of the metal operating couplers and plastic domes for the dome cars - some of these have warped badly I guess due to the plastic used. There is someone on ebay selling repro fixed couplers and they work well, but I am looking for the metal operating couplers. Any help is appreciated!
