The engraved logo are the earlier first generation (86?).
Ok, then! I have a four-pin crankset marked "11" in a rectangle, so it's a 1985. It has a printed shield logo. It's left arm has an inverted triangle (point up) and a "22" in a rectangle, also printed logo, so a 1986. Also I have a Chorus (I think) with both the drive side and non-drive side marked "41" in a rectangle, so that is ???
Is the same date system pertinent for Chorus, Racing T, and newer items?
