Joe, It is hard to see just how much original finish,blue,or case colors remain from your photographs.It does not appear that any of the original finishes or case colors remain. This is not what you want to hear after your honorable effort in posting the photos. As with any sale of any classic gun, it is only worth what you and a prospective buyer can agree upon. If I were going to insure this gun I would insure it for somewhere in the $1000- $1500 range. Original condition is everything when appraising one of these guns and the lower the % of original finishes, Blue, case colors, and varnish the lower the value. I hope this helps. You may find another opinion that is higher but condition says it all.
