I noticed in the ad that he dodged the mention of "original wrap". The wrap looks a little too "modern" to me, looking more like the style of Rogers Onyx wraps than the smoother strata of BOP from the era. You never know, though, and I'm no expert. Definitely a "wrap into the shell" pic would close the case.
If it DOES turn out to be a rewrap, what does the vintage drumming community do? Does somebody warn potential buyers that they're not really buying a $1600+ drum, or does everybody take a step back and rely on the "let the buyer beware" mantra?
