After I posted, I went back through some of my Japanese bicycle catalogues and found references to the Compe-V in 1972 catalogues but not 1971. So, it looks like 1972 may be the first model year for the Compe-V.

Component date codes are always appreciated but don't make a special trip to get them. The next time you have to go to shop or are in the vicinity, will be fine. TIA.
