TGR M Class Steam Locomotive

TGR M Class Steam Locomotive body
HO scale (1:87)

Designed around the Hornby TT:120 Flying Scotsman mechanism and to be printed on a resin printer.

This version includes replacement cylinders for the mech and requires the removal of the Hornby ones. It's a little more difficult to get put together.
There is an updated body design at the link below that doesn't need you to modify the cylinders of the TT:120 mech. It's much easier to get running.
