I've recently acquired a WJ Davis S/S 12 bore which is in good useable condition but does have some slight looseness on the L/H hammer. I'm not sure if its the hammer which is worn or its seating and don't know the best way to repair it. I guessed that building up either the hole or the shaft may be the way but would appreciate any suggestions as to the right way. Thanks for any help you can offer.
