Probably 1966 - 67 the last year of the Kodiak until it was resurected in the '80's
Many of them were blemished or factory seconds that were camo painted to hide finish defects and such. although if some ordered a camo model and rhey had no blemishe ones, they paint a first run model.
Regardles of being blemished or seconds, they were all solid bows. Bear would not hide a critical defect and sell it.
On many "blemished" bows you would have a hard time finding the defect. If there was something really minor, Bear would not let go out as a first quality product.
