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.
Please do not PM me asking for support. Please post your questions in the appropriate forums, as the replies it may receive may help all members, not just the individual member. Kindest Regards, Darryl
