The thing is when these knobs crack the small pieces are not usually saved (probably was very long time ago too) so I have what I have now, no pieces.

Gosh.....somewhere in ole Russia I'd go to a local craftsman and he would for a bottle of "the white one" make me a sample that no expert would tell apart from the original.

Actually, not a bad idea....I have some connection in Russia radio world, might as well ask if they know someone.
