Sellwood Cycle Repair has a few interesting things on ebay; a Spence Wolf-built wheel set with Cinelli Bivalent hubs and Super Champion 58 rims--don't know if they're 27" or 700c, though. Also a Wolf-modified NR rear derailleur with long cage, and a pair of high flange NR 28 hole rear hubs.
Happy hunting
