SJP-Tn08 Rio Grande Southern 4-6-0 #20 tender This is a tender for the RGS 4-6-0 #20 conversion parts (SJP-St20). It is designed to use the trucks and electronics from a donor Bachmann On30 4-6-0. The Bachmann hardware can be used to mount the trucks and pickup plates, but you’ll need four M1.6 or 0-80 flat head screws to mount the shell to the frame. The frame is setup for On3 height couplers, but shims can be used to lower it to HO height if desired
