It is a 1950's bow and it is a collectors item. Par-X made several models as well as Grimes and other companys in the 50's. Some of them were very intricate with nice detail in the limbs. They also came in several colors. Aluminum, green, red, and black. None had a metal string. The majority would fail after time with some shooters being injured. You can see pictures from archery clubs in the 50's and every shooter on the line would be shooting one of these metal bows. It is best not to shoot them today and keep them as one of the few surviving metal bows from the 50's. Value varies depending on color, maker, and detail. I have sold them for as little as 15.00 to as much as 50.00.
