OK if anyone could tell me the value of this bow or where to find a collector who could tell me the value,I would really Appritiate it.

Ok my dad has this old Browning Cobra 1 recurve he got it in or around 1971,He wanted to sell it the other day and a person at a pro shop told him she would give him $150,but that she might be ripping him of at that price and that the bow could be worth alot more,

I tried Browning but the have no value listing on a bow that old.

Could someone please give me an idea of where to go to find out the value of this bow? please.
