Shane -
Nice quiver! Yours is the last model of the Northwoods, which has the zippered pouch. The zippered pouch Northwoods were made in two slightly differed models.
Bear made a number of Northwoods quivers that preceded the zippered model that you have.
The Northwoods quiver first appeared in the 1941 Bear Archery Catalog.
The CD that Ron mentions does not include any of the very early Bear Catalogs from Detroit, many of which show and describe the early Northwoods quivers, and other Bear equipment from 1933 to 1947 when Bear moved to Grayling.
At points in time there were many different optional features available on the Northwoods quivers. Some models of the Northwoods quiver were extremely versatile in that they could be used as a hip quiver, center of the back quiver, or over the shoulder quiver for either right hand or left hand shooters.
