Retired modeler ran everything on a test stand it seems. Note photo's of lugs, side of piston and muffler. I believe ran for tune / break in only. Lugs do not show witness marks from screw heads but do appear to have been clamped in something like a Tatone test stand.
Comes with original box that is a bit tatty with no foam inside. Original Allen wrenches and muffler bolts also included.
Check the photo's closely. You won't be disappointed.
