Hi Craig, and

on a good score there mate.

Unfortunately it's got me stumped, I've never seen anything like it....However, I like you, suspect that it is a British made machine,and you could contact the Old lawn Mower Club;
webquery@oldlawnmowerclub.co.uk and they may be able to identify it for you.

Best of luck with it Craig, please let us know how you get on.
