That was the premier target bow from Bear which was introduced around 1963. Those that I have seen have remarkable wood or phenolic, and lots of it, making it a very stable and accurate bow. Most were close to 66-70" with weights usually under 40#. I've had an eye out for a 64" closer to 50# but find they are really scarce. Values can be all over the place, but most nice ones in good to excellent condition tend to go for under $300.
