Gentlemen, I have recently acquired a Brno factory sporter in 8X57 caliber that is the full stock rifle version (model 22f),. This one has the factory 4X Optotechnica claw mount scope attached(with coated lenses no less), along with spoon bolt and double triggers,and was mfg. in 1946.I have labored in vain to find an original or copy of any catalog that lists these rifles in that time period.I believe they were imported by the Thalson Co. of San Francisco. Does anyone have any info on these models,along with prices and calibers offered? Thanks, Marcus
