I got in this pair of Cary metal shell F3s. One on a Proto Power frame and the other on an Athearn blue box frame. I am going to put them both on Genesis frames with DCC and sound, but it will take a good bit of milling inside the shell.
I am still looking for a couple Atlas GP38s in the Bangor & Aroostook black, red, and grey paint. If you have one, or more, that could be for sale, send me a message at firstname.lastname@example.org
