Hi Geoff, welcome to Outdoorking.

That mower looks interesting. Do you have the chain cover and/or grass catcher, and are you going to get it into working order?

One of the interesting features of the mower is the engine, which does not look like any Villiers I can remember, but is a lot like a Tor I used to have. More information on it (and more pictures) would be of interest. Hopefully Deejay or willingworker will help us out with some background both on the mower, and SB's use of that engine.
