Looks like your getting a lot of good advice, so I thought I would add my own reassurance. I have just recently gotten into the "vintage" older recurves with the guidance of my uncle. I took my last two animals with a '68 Bear Kodiak Hunter of #57. I shoot the heck out of it as well, no problems. I was just given a '58 model Bear Cub with the dual shelves, and at #50 I run arrows through it like crazy....gonna own 'em, have to shoot 'em! I just purchasd a '68 60# Bear Grizzly and have been shooting it often as well. All these bows have great glass and very little stress cracks, except the Cub has a few more stress cracks....vertical of course. This is Ok. You may find it satisfying to find arrows and heads of the same age on e-bay or such and use them with your bow as well. I shot my whitetail this year with that Kodiak Hunter and 60's Bear Razorheads and 60's Browning Cedar arrows. Have fun and good luck!
