So, what makes you think it is a 1959 bow. I'm guessing it a 1969.

Hilarious moments in hunting. You got any?

One of my best ones was when I was bowhunting in the end of October. It was a really cold day. 

I was using my Heater body suit. I was toasty warm, sitting on a three legged stool.

I fell asleep and rolled off the stool, ending up face down on the ground. I was on a slope and my head was lower than my body. I had a heck of a time getting up right.

Cool Video, looked like a great time!

Another good reference for arrow shaft tuning, scroll down to bare shaft testing.

Excellent video! I really enjoyed it! Nice shot.

Check out this video, very helpful.

Do these boards have the right grain?

I had a Black Bear Hunter, and a Stag Hunter that had blonde maple risers, and didn't have string grooves or tip overlays

Definetly look different!? Still a recurve though. The shorter ones always seemed to have more "curve" due to the angle of the limbs coming off the riser.
 Like the difference between a K-Mag and a Grizzly.
I have a bunch of old Bear recurves and all of them seem to shoot best at about 8-1/2 inches

Here they are from the same '77 catalog. You can see the difference in limbs, and the BBM doesn't have grooves on the limb to keep the string centered either. K-mag at 49" and BBMag at 51". I wonder if brace height would still be about the same between the two?

I know that the black panther models were for big box stores, and that they were never in the catalogs. I wonder if it was just a newer design that got rapidly overshadowed by the up and coming compounds? It looks a lot like a shrew bow to me when strung.
