I've got a 91. It's Tange. Here are some pics...had it repainted a while back, it was original grey with purple decals, a little too much for my techno-Amish sensibilities.

This frame is actually going on a hook for a while; it's a bit big and a bit tight, geometry-wise, and I'm in the process of buying a Rivendell Romulus frame which should be a better fit in all ways. I was looking for something along the lines of a vintage Specialized Sequoia, but couldn't find anything here in Philly after months of scouring CL and ebay.
