O.k. the diameter of the wire is real thin but on the other hand if it was possible winding a HV coil 60 years ago it should still be possible today- or am I wrong?

Greetings Josef
Possible, but you may get a different high voltage or different "stiffness" (variation with current) of the high voltage from the original, as it may vary with the dielectric constant of the potting compound, which affects the resonant frequency of the secondary. The difference in stiffness will not be a great worry in a set that uses a shunt regulator.
