Well, it is certainly possible to kitbash an SD-7 from AM or even AF GP-7/9 shells. I'm not sure were the early SD style trucks would come from. A simple metal frame ro extending the AM frame ought to be relatively simple compared to the trucks and shell changes.
I would have to check, but I think both the SD-7 and SD-9 were imported in brass in the 1980's. They would probably be a viable project today. I found a prototype roster here: http://users.inna.net/~jaydeet/sd7.htm They appear to be mostly a mid-western\western engine, except for B&O and B&LE Pieter Roos --- Scale S Only <[EMAIL PROTECTED]> wrote: > Hi Guys! > > I often wondered how long it would take for Ron B. > at American to come up with an SD7/9 loco.
