Looks like the gun wore a Beavertail forend. Based on the bluing wear on the barrels. I doubt it was original.

It is my personal opinion that your lower rib is too mangled to be able to fit it reasonably and re-use it.

I have a set of 1894 barrels available for sale, but they are Damascus.

Ther is a good amount of these guns out there in well used condition that could be used for parts.

Where did you get your stock from?
