Just bought this grizzly monticello MN. Any Idea how old she is? Thanks serial # KD3393

It's probably 1975-76.

The Super grizz didn't appear until the mid 70s and the K in the serial number was replaced by SG in 1977. In 1978 the company had moved from Michigan to Florida and the Super Grizz was no more...until very recently when they started making it again.

Thanks buddy! I was just telling my buddy I doubt it was an 80's bow.
