That bow is not from 1953, its from the late 60's. All bear bows of that era had the cananda patent 1953 decal, its deceptive. Most of those bows I've seen have always been target bows under 40#. I would guess from the white glass, that this bow is a target bow not a hunting bow.
Those Tamerlanes were some of the most beautiful sculpted wood bows made, period. That model was Bear archery's top of the line target model in the late 60's.
This type of bows were replaced shortly after by bows with detachable stabilizers.
As for monetary value, the ones I've seen on **** go for around $300 bucks.
