This is of course far from definitive but I'd say they are Campag or Campag copy (but then Dura Ace was Campag copy in that era).
I think the grease port on the front hub marks it as a Super or Nouvo Record large flange hub, suspect the rear may be large flange Gran Sport (lack of grease port).
I think the front is French, possibly Maillard, Simplex or Prior(Maillard copy) going by the drilling and QR design and the rear is Jap - maybe Dia-Compe. The front hub will take a mirror like polish if you are going to renovate them. I had a similar pair on an old Motobecane.
The rims maybe early Mavic but I'm thinking more Wolber.
I think I can see one pair here:
And this nothing to do with it, but they are interesting:
the flanges look pressed to me, suggesting both cheap and old possibly. They don't strike me as campag or maillard (skewers are wrong). What are the bearings like - i reckon a bit of brasso/solvol should get you a nice shiny set of hubs.
