Brian,

The 'guts, hammers & sideplates' will have to be made from scratch by someone with incredible skill and will cost a LOT of money. It could run into the thousands of dollars.

If you are INCREDIBLY lucky you might be able to find parts that will work but won't really fit and will never be original.

This gun (sadly) as described has reached the status of wallhanger and is probably better for parts in some other restoration. I have one 'just like it' hanging over my fireplace.
