Just a note.
There may be a misunderstanding, judging from some of the replies.
Not arguing against (or for) the utility of sleeving. I'm asking about market values...and that implies a question posed more to prospective buyers than to sellers.
The example: Given two Boss guns of the same period, stock dimensions, etc., one with good or borderline original barrels, and one that has been sleeved...what would the price difference be?
Would the sleeved gun sell for half the price of the gun in "original" condition?
That's the question.
Thanks!
