I'm pretty sure there is no such thing as an endless clamp M700 front mech. It certainly never existed in any Shimano catalogue that I can see - which means god knows how that photo above came to be. Maybe it is a cobbled together Deerhead/M730/M735 abomination?
It's kinda thrown my build now.
We're pretty sure the bike is an 87 and not an 85 like first thought.
Having a mix of Deerhead and Suntour parts will mess with my OCD. As will mounting a later gen front mech. Plus the roller cams are Suntour.
So if it's an 87, I might just run with 87 6 speed XT - I have most of that kicking around and I think an M730 31.8 will be a much easier find - and I can swap out the Suntour roller cams for XT U brakes. Tho I don't have many fond memories of U brakes, they were always shit!!!
Gonna be a slow burn this one. Will look at getting the frame repainted and source the parts whilst I wait...
