Dave, the serial number on the KMag starts with a 7 so I am guessing its a 1967. Here's a photo of the back side.
Gary, it's Dave's fault I'm still shooting both ways. If he can do it, by golly I'm gonna practice until I get it right. I started practicing righty last fall when I discovered, after 50 years as a lefty, I have become RED.
I took both bows out this morning : better groups and point-and-shoot with the righty '62. Both are like carrying a feather compared to the mass of my other bows.
