Behring custom made bike Hoping someone can help me as I don't know much about bikes.  

I bought a 10 speed bike at a garage sale which the owner said was custom made by a bike maker in St. Louis, MO.  She said the frame was chromoly steel.  The frame has the name "Behring," which I assume was the builder, and there is a label on the bottom tube which says "Columbus Tubing."  

Is anyone familiar with a bike of this description?  I have some pictures if that would help.
Apparently George Behring used to be a framebuilder in the St. Louis area, and was a racer and a member of the Saint Louis Cycling Club. Unfortunately, like many small builders of the 1980s, there's very little information about him or his bikes on the web.
