Hello to everyone and I hope that you can assist me in my search. I have been given a very old rotary lawn mower which I think is American but cannot find markings. It has a Briggs and Stratton Industrial Commerical engine. 17 inch rear-drive back wheels - self-propelled. Picture attached - does anyone recognise the model as I need a V-belt for the rear drive and hopefully a manual. Thank you everyone for your help from a very hot France!
