After a long search I found my CEP. Brown/black flecked bakelite razor, with a Zaiss-head that is found on the NEo-Ras/Gam/Lux series of razors. Has the same claspingsystem too. Two differences however: the baseplate is marked "Made in France", and the metal clasp that holds the head in place is not triangular, but half a circle. Turn the handle half a twist, and the head can be steplessly adjusted into a slanted position, anywhere between 0-45°.
