Long story, about 40 odd years ago me & my mates found an old piece of farm machinery on an abandoned local smallholding, It was a Blackstone Hay rake, a ride on job designed to be towed behind a tractor, with a great rown of curved tines about 3ft long. Wheels about 5ft across. We appropriated it & attempted to get it home one summer holiday. We actually managed to move the thing over 3/4 of a mile through the woods until someone nicked the wheels one day & that was that! I had the seat shortly after & still have it. The rest of it is still there. Today my son & i re discovered the wreckage to our surprise it hasnt rusted away. That machine has been out there in the wind & rain since WW2 & its still largely there. Parks dept tractor had tried to bulldoze it & snapped a few of its rake tines off which i have bought home. Any ideas what the hell these were made of? They are rusty but still strong & ring like a bell when you hit them. Im thinking this has got to be some good iron & am thinking to reforge into some blades. Any ideas what they used back then?
