Thanks Rob, seen that bit on wiki, I’d of thought there would be more info out there on them, did find it strange being an offset scope during that period.
The rear sight is missing also on the one I’ve purchased plus the fore sight has been replaced with what looks like an AJ parker one.
Be one one of them rifles I’ll have to store till bits show up. In the meantime think I can knock up some sort of side mount so I can retro fit a repro K98 scope bracket etc.
