I bought at auction a Brit Steel helmet, having given it a good clean and got the leather fitting supple again it looks OK. The are no makers marks I can see. The edge has a rim put over it and there are 2 rivits either side of the dome to hold the strap attachments and a screw in the top of the helmet that goes through and holds all the fittings in place. There is a small Blue (black ?) Yellow Red flag painted on the side. Can anyone tell me if this is WW1 or WW2 helmet. I'll try and get a couple of pics up later. Thanks.
