As long as there's no water damage,then that's not a bad asking price,you could probably get him down lower,
The wrap is called sky blue pearl which has badly darkened to where is looks like black diamond pearl..
It is NOT repeat NOT the same wrap as Ringos Ludwigs which are Oyster Black Pearl and look nothing alike.Take along a pic of Ringos drums if you have one to prove your point.That will also help lower the price.
Looks like a 22/13/16 with a 5.5x14 classic snare with a P-87 strainer..
Get over there NOW,don't stop,don't pass go.......do it NOW.At the very least you have a nice vintage players kit.
