even if it had old mounts it is highly unlikely you could mount new optic in them. i have looked through those old scopes (zeiss, hensoldt, oigee,...)with just elevation dial-style knob on them and from optical point they are next to worthless equal to $60-$80 tasco. many have solid brass tubes suitable for use as hammers, but that's about it. the new 30mm helia is first class i would say beyond reproach. ;)\
some folks collect old stuff and that's ok. i had early 60s 3x meopta scope left over from old brno .22 which i scoped with new leupold 2-7x rimfire in new mounts. i gave that old czech scope to zg-47 owner because it fit his mounts and he thought it was best thing since sliced bread.
