Doing the math, if one has the engraving at 3K and a restock at 3K and the wood at 1K and 2.5K for metal work (breechballs/safety/rebates/polishing/case coloring/rust blueing), then you are getting into the $9,500 range and that doesn't count the cost of the donor gun. Added another $1,500 or more a mechanically sound 20 gauge ejector Sterly (if you can find one that cheap) and you are at 11K. If you use the best fellows in the business to do all the work, you may or may not get your money back when you are dead and gone.
FWIW, the gun on Auction Arms needs a serious refurbishment IMO. Just a recut of all the engraving is probably $1,000 give or take. Then you add all the other stuff and a soup to nuts refurbishment might run 3K to do. It all adds up for sure.
