Wow Huvius - you certainly seem to find them! Trebly good being a bore rifle, as Jens says, a rare find

The Hammer replacement is ok for you to shoot it (range reports looked forward to)

AH hammers may be slightly difficult?? to make, the lip under the hammer is to catch in the slot in the top of the falling block to prevent accidental discharge if the hammer is down when lifting the block with a live round in the chamber, stopping it "flipping" and firing the round [IIRC we have discussed this before on one of the forums]

Good luck to you as usual for shooting, I wish we could shoot our rifles with less hassle here in the UK!
