That "little gun shop in the middle of nowhere" was the primary conduit for the import of many select-fire and converted-automatic firearms into Canada back in the 1970s and 1980s. Owned by Mr Peter Wilke, "Ontario Guna and Tackle" (OGT) in Kenogami/Swastika ON worked closely with international surplus arms dealer SIDEM out of the UK to import all of the ex-OPP ERT FN C1A1 rifles still in Canada, all of the Original AR10 rifles and parts kits that came to Canada and then down to the USA, and many of the eclectic "odds and sods" like those semi-auto L85 rifles that popped up in small numbers. My CA C1 SMG, CA Uzi, CA PPSh-41, Russian AKMS, and several others within my collection were imported from SIDEM and sold by Peter Wilke, either as part of his Wife's business holdings or his private collection. He ran into some legal difficulty regarding CA conversions in the 1980s and as a result had to transfer all of his business dealings to his Wife's name. Business as usual continued until Peter breathed his last some time in the 2000's if memory serves....
Lots of folks know of the big distributor names like North Sylva, and the like. Very few know that one-man-act Peter Wilke topped them all during the 1980s.... He was prolific!
