The find of rares:

10 kV Zsolnay small Deltas. The 10 kV open wire lines was very rare in Hungary. I have not seen before this like Deltas and they have interestind markings: "PODAR 1952" I don't know what means it.

The white ones are 20 kV "Soppk head Deltas". They are the first generation of outside fuse holding on the transformer poles. They are DRASCHE Budapest. This type of Insulators were used in vice versa. They are very rare already.
