Check with R&B Records Run by Val Shiveley, who now seems to have four million 45s in his Philadelphia store(which is actually in Upper Darby). There is no catalog, and his stock isn't posted on the internet-I always would just walk into the store, and hand one of the guys my list (Val was usually on the phone, and usually yelling) but I understand that you can send your "want lists" by phone, fax, or mail My experience has been if it is anywhere, he has it--P.O. Box B, Havertown, PA 19083. Call (610) 352-2320 or fax (610) 352-8199. His prices are always fair, and he has reissues when they are available as well as the originals.
