Typical telephone insulators from 1920 - 39. 1st, 2nd and 4th insulator are in typical color. 3rd,5th 6th and 7th are in wery rare colors. last piece has'nt upper groove. Some insulators was made in broken form. Insulators in that style was made by:
- Huta Vitrum
- Huta Rogów
- Huta Robotnicza Nadbużanka
- Huta Dubeczno
- Huta Niemen, probably since 1935.

Two Niemen's made before 1935. That insulators was made in three sizes too, but I have got only the bigest size.

That insulators was made after 2nd war to 1960's in three sizes too.

And after 1960's insulators had two sizes but more colours. first six insulators are in typical colors. next pieces are wery rare.

Power insulators. Made since 1945 to 1989. typical colors somethink like in upper picture. differents are wery rare.

on the bottom are smaller power insulators. History and colour are the same like upper. On the top are rare insulators. 1st and 2nd rae made after 1970. It is not common type, and in dark green it is wery rare. two insulators with groove are Niemen's from 1935 - 39. I know only that two, one broken in Zoltan's collection and two on a wall near warsaw.
