General Information
No model number found on levers or body. Model number given is a best guess.  Works with 74XX series Dura-Ace rear derailleurs (and some Mavic 8sp!).  The Dura-Ace 8-speed STI brake and shift lever combos (brifters) came in 2 versions (scooped out and non-scooped out levers). The problem is that the 7400 series brifters do not have a model number stamped anywhere on them to designate the difference between the 2 types. It is believed that the scooped-out variety is lighter and is a later version such as 7403 or possibly 7410. I have uploaded photos of the back side of each type. The scooped out version is shown new in the box, partially obscured by the plastic.

Shimano's top of the line race quality component group in the mid 80's through the early 90's. The 7400 series Dura-Ace group saw several interations including the introduction of 6 then 7 and finally 8 speed SIS shifting. Eventually upgraded with 7410 parts before finally being completely replaced with 7700.

Dura-Ace was developed to give the professional racing cyclist a fraction-of-a-second advantage that can spell the difference between victory and defeat. Advanced functions like 8 speed SIS, Super SLR brakes and Shimano Total Integration provide the most refined feeling of control available in a group today. Ultra high-precision mechanisms, quality materials and rugged construction assure that Dura-Ace takes all the punishment that pro-level road racing can dish out. (1991 Dealer Manual).
