The cable guides on my bike were introduced in 1978. The numbering on the seat tube was introduced in 1979. Since I don't have numbering, it follows that my bike was produced in 1978. Thank you T-mar!
Do I also have the "lethal" fork that was supposedly prone to failure? Mine has a round section, for sure, otherwise I don't know what to look for.
