Yes, these look like Diazed II (medium size) fuses, although the panel(s) doesn't look like the ones I'm used to.

The Diazed is a pre war design, which means that its spread needn't be limited by the iron curtain. I know that they are used in Germany, Scandinavia, Ireland, Switzerland, Austria and I think also in former Yugoslavia. And Poland it seems. It is very likely that they are used in many more countries.
