Does anyone have any reference book,video or other media showing this action from 1875 disassembly? Only did surface cleaning so far.This gun is pictured on Mr Gunderson's militaria sight (sold).

Perhaps related to Grant and Hodges patent guns?

If you need a book it figure it out , then dont do it .

In my professional life I provide patient care.You better hope I use a book to help me figure it out.The same with guns you work on; over the decades I have learned to use every resource available to carry out a project correctly and safely.The wrong mistake can injure or kill you.The knowledge base of this and other forums is part of the reason for their existing.

Excellent reply, herath1.
