Swedish Civilian & Sporting Firearms
Look through there and you may find some old threads relating to the rifle. If not register and ask about it. They're very helpful.
Kollmorgen made 'scopes along with alot of other products. I think their first rifle scopes were made in the '30s and were sold as 'Stith' brand. The later internal adj. models were Kollmorgen brand (BearCub was a very popular model). Either Redfield or Weaver bought the company out in the 50's or 60's I think.
Do a search on the company and you'll probably find alot of info on them,,and corrections to my recollections!.
I think they're still around in some High-tech industry.
