Navy Arms 1863 Springfield Hammer Question

[103]

A friend in the living history world has a problem with his Navy Arms 1863 Springfield (I believe Miroku). He has had it for a couple decades, and it appears the hammer is a bit soft and has rounded out a bit around the tumbler. Tumbler is still square, but the inside of the hammer is rounded. He asked me to find a replacement because I have basic 'smithing experience. I have never worked on any variation of an 1863 (repro or original), so I wanted to ask you guys about it.

At first I wondered about welding it up and cutting it, but that would require precise angles and distances and more work than I would really like to do (and I am already iffy about the hardness with how rounded it is). He said he would be fine if I simply replaced the hammer. Does anyone know where I can find a replacement hammer for this particular gun?

I appreciate any help you all can give me.

(Note: I am doing this for free--he's just going to pay for the hammer and probably feed me or something.)

Should be able to find this part easily? S&S Firearms, etc.

Have not been able to find a NA/Miroku 1863 hammer anywhere. S&S was the first place I looked.

Thanks for the reply. I guess since it's much older, it would be a problem. Let us know how the repair goes, and good luck!

I have an 1863 repo hammer tumbler & lock plate, Not sure if its the Japanese Miroku but if you like I'll get some photo's and dimensions for you.

Thanks

I had him double check the gun for me. Turns out it’s Pedersoli. Still can’t find any of those. Any idea if an original hammer is compatible with a Pedersoli 1863 action?

There's a Ped. dealer in New England, Flintlocks, Inc., I believe. If he can't get one, from Ped., I wonder? Let us know how you make out.
