It is one of the first series of the Bear bow quiver. The first ones only held four arrows , later they held either four or eight. Bear pioneered the bow quiver.
Depending on what year it is, it may have decent collectors value.
Later. they came out with the double spring arm model,then the sigle spring and screw down (converta-quiver) then the double screw down which is still made today.
The old ones are brown,like yours. After taht all are green.
