I'm guessing the year on this as a 1977, late 1976 Dura Ace date codes.

Much too large for me, I picked it up for all the black anodized Dura Ace components. Even has black DA hubs with tubulars. Considering putting the parts on my 1973 Sakae Professional, but it might be too much black (Sakae is black and chrome). Frame is up for sale, so wanted to post the complete bike. Tough 52/44 gearing. Kind of surprised the brake levers are not black. As luck would have it, I already have DA 1st generation levers on my Sakae, and they are black (with silver calipers). So a swap of the two lever sets at least makes sense.
