Now I don't know about the rest of you, but this, IMHO, is about the coolest bit of info I've seen in a while! :-D I just spent a few minutes with Grant's little code list and inspected the wide range of Shimano parts in the basement and it pretty much confirmed it for me (not that I doubted it, I just wanted to see it in person!).
Thanks very much for that info Grant. That'll be pasted in the shop for future Shimano dating purposes! And it seems to work on non-Dura Ace parts as well! Too cool.
