I own a ~1975 14" cylinder/reel Scott Bonnar mower that I intend to restore. It belonged to my Uncle and hasn't been used for many years but is complete. The engine cowling date suggests 1975 as the year of manufacture of the engine (2HP B&S) but there does not seem to be any ID plate on the mower itself. The front rollers are timber cylinders and the drive is via a serpentine belt rather than chains.
I've posted a similar description in the Restoration forum.
I'll upload a few photos soon.
