As a faithful reader of this forum for going on about three years or more now, and living in a city where the desire for vintage gear of all types is very strong, I still have to say that almost no one wants a re-wrapped set. One possible exception being a player that finds a dream vintage set and the wrap is so damaged as to leave the shells vulnerable to further damage when gigging out. And even in that scenario, what are the chances you are going to pick the same wrap that player/buyer would choose? Even if you chose to go with the type of wrap that was originally on the drum set, or a pedestrian (ie, low key) wrap choice, like blue sparkle, you are still going to hear "68 Ludwigs? Man, something just looks a little off about this set... That wrap looks a little... Hey, is that a re-wrap? Uhhh, this set just doesn't have the mojo that I'm after..."
And at that point the potential buyer will have almost, if not completely, lost all interest in your set.
Players that are interested in vintage drums want them to be vintage through and through. The sound may be there, awesome, but the wrap is the visual aesthetic that, for most, needs to be there as well. Sets that have been taken care of through the years are good, closet queen time capsules obviously go for the most, but if anything actually needs to be done to a set, I find that buyers would usually like to make those choices themselves.
And, of course, as it has been noted by others here, collectors have ZERO interest in re-wraps.
Due to all these factors, especially when dealing with American or European vintage drums, I've sort of come up with a little motto: "Leave 'em original, and leave 'em alone."
