I've owned a lightweight road bike for years without knowing what it is, and hoping someone might be able to help me ID it. It has chromed drop outs and nervex style lugs and probably built for 27" wheels, but the most interesting part of the bike are the chamfered seat stays. I've only seen these once before, in a book called "The Custom Bicycle", where they were not identified but pictured. Thanks ahead of time for any help.
