the 650b has the cable routing as part of the bottom bracket
the 700 has a screw on cable routing
The chainstays:

Notice the 700c has indented chainstays for chainring and tire
clearance - the 650b ones have been shaped differently going into the
bottom bracket.
In looking elsewhere on the net I've seen very few with the indented chainstays.
Rear dropouts:

Completely different dropouts - the 650b has only one brazeon for
racks/fenders at the dropout - the 700c has 2.
The 650b's dropouts are obviously not even the same. They remind me
more of the romulus/rambouillet drop outs. In looking at more pictures
online there appear to be 2-3 different rear dropouts in use on hilsen
builds.
I'm sure these differences don't amount to a hill of beans - but I
found it interesting comparing them. Does anyone else notice any other
differences?
