Hey Chuck, I have a Grizzly that starts with 65 in the serial #. And I know it's from the seventies and one of probably the last ones built in Grayling. This is my second one ,and I like how it shoots. I picked it up off a guy at work, with bear spring arm quiver for 35.00! Don't find many for that price. Mine is missing the medalion, I bought one to put on ,and from the looks of it , it would be raised also. Check out the trad history/collectors section and ask over there for more info. Those guys know their Bear History, Good shootin, Steve
