Thanks Jim. That's the weird thing Jim, I should have really photographed the damage, the grinding was on the side of the cross guard. The worst of the damage was in-line with the damage that can be seen on the bottom grip on the right hand side, picture 1, post 1, where the grip is angled off. I can't work out how anyone could accidentally grind this or what reason there would be for deliberately doing so. I am pleased with the repaired cross guard which I have completed and re-blued this evening. I will post pictures later of this bayonet which has a blade in excellent condition.
Peter, why do yo say those grips are modern repros? I'm not suggesting that you are wrong but I was wondering how you could tell. I wondered why they weren't a great fit on the bayonet when I tried them for size this afternoon.
