HO scale (1:87) model of a Massey Ferguson 750 or 760 combine produced at the Brantford, Ontario plant. Production ran from ten protoypes built in 1971 to 1984. The model has a separate platform, ladder and railing so it can be modeled as a flatcar load.
Four successful test prints have been run - full assembly instructions are in the Tips and How-Tos Forum:

Decals are coming soon.
A precision sprue cutter like the Intermountain BB-1015, Micro-Mark #82393 or UMM-USA GMT01 is required to cut the parts from the support framework.
