Another agree with Mike. I've been down this same road to a degree. A fine English stock blank isn't inexpensive and restocking is probably circa $3,500 (not counting the blank) from Dave V. Throw in the celebrity folks who did the barrel blacking and new action colors and you might be exactly into the dollars he is asking for, (counting the cost of the original gun of course).
I'd like to see a few more pictures and have measurements etc etc, but this is no doubt a project that hit all the marks for the original owner.
PS. I doubt if anyone could replicate this exact gun with the same craftsman utilized at the current asking price.
