I have a Bear Grizzly marked with serial number GR06486. My research shows these GR numbered Grizzlies were made from 1981 thru 1984. Bear had been moved to Gainesville FL since 1978. I see the white markings on my bows trademark still show it made by Bear Archery in Grayling, Michigan. Was it a fluke to have the Grayling trademark at least 5 years after moving to Florida? Does this make this bow unique? Any of you Bear experts ever seen this?
