I have a 1899C s/n 51445 in .303 Savage that has the hammer rebound spring missing. I have research quit a bit and have seen several pictures of breach bolts but none of them look the same as mine. there is a second screw .420" below the hammer bushing screw that i believe secures the hammer rebound spring. The shank of this screw has spiral wear marks on it. I would appreciate help finding this part or a good breakdown of this model. I live in Alberta Canada.
Thanks
