I recently acquired a GE Lewis martini rifle. I have been spending time cleaning and have a chamber cast made.It is a 577-450. I now have a few poor images but am asking if others
with more experience can give me pointers.
I have one lead on a new stock and person to inlet.
What kind of sights- front and rear are these.
Are there sources for this old ammo.
What were the conversions from the 577-450 and has anyone used inserts in these rifles.

Thanks ahead,
Frank
