I have just acquired a vintage 4x telescopic sight that is marked "DISKOP 4x 2305" fitted with contemporary pair of rings.

When I bought it all that could be seen was the marking "4x 2305" as the "DISKOP" was covered by the rings and had been for many, many years.

It lookd German and very much a ZF4 type "clone". So does anyone have any info on this maker please?
