I'm planning to make a model of an Arkansas & Missouri Alco T-6. I was at the GAT Show at the Orange County Fairgrounds yesterday, and picked up S1 and Rs1 shells to start the kitbash with. I think the S1 shell may be Model Power. The Rs1 is from an old lifelike toy. I plan to use an old Athearn sw7 body for the walkways and the sw7 drive fitted with a can motor.
