I'm retired from gunsmithing and going through boxes of parts and pieces this question came to mind. If a bare receiver was found that the S/N showed a provenance such as a surrender piece from the war on the plains linking it to a well known or famous battle would the receiver be of value left as is or be of greater collector value as an assembled rifle using correct parts to the original configuration. Of course the rifle would be described as an assembly piece and not passed off as original. This is taking into account that a "C" is not stamped on the underside. I did once encounter a Bannerman with a condemned receiver many years ago and I should have examined it closer to see why. I am just curious to see what opinions everyone has.
