This is a 1950's version, identified via the barrel adjuster (ended sometime in the 50's) and toothless ball-bearing jockey wheels stock from those years (later 1960's and 1970's had plastic toothed pulleys)\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan style=\"font-size: medium;\"\u003eIn 1951, Campagnolo shook the cycling world with the first prototypes of this GS derailleur which was the foundation for most modern derailleurs before Suntour's slant parallelogram.  The first couple years of these were made in low numbers, and sell for crazy money (several thousand dollars!).  They were made of bronze, and plated with steel\/chrome.\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan style=\"font-size: medium;\"\u003e\u003cstrong style=\"font-size: 10px;\"\u003e\u003cspan style=\"font-size: medium;\"\u003eCondition\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan style=\"font-size: medium;\"\u003eNear mint lightly used shape.
