Holy cow, lots or rare, expensive Mavic stuff on that build! I haven't seen one as built to the edge of the envelope as yours was.
Weren't these solid rear disc wheels used more on 24" front wheeled TT "funny" bikes and not the "straight" frames like this Peugeot Pro?
It's a fantastict build with definite serious "tout mavic" flavor, but I can''t seem to connect the frame to the wheels when I look at it, if you are meaning to build a "period correct" bike. Maybe it's more of a period "special" instead?
