This is not boasting, as it merely substantiates the depth of my sickness, and that's never anything to brag about. But, I calculated some years ago that I'd had about 1500 bows by that time. 90% of them were "vintage" laminated bows, mostly classic recurves. Although it's fair to mention that what I call "vintage" now,sometimes meant I was buying a bow from a popular bowyer at the time! For example, I only bought one bow direct from Jack Howard, but have bought 7 or 8 since! Which ones are vintage? The count I took at that time, was that I'd had only 2 old bows fail, about 5 self bows had failed, and 4-5 custom bows had failed. And, both the 50s Bears that did fail, were suspect, in my mind anyway. Their condition just didn't inspire confidence! If you are worried about old bows, do the math on that 30+ years of collecting bows and shooting all that I could! It's now over 40 years and there haven't been any more old bows fail. No offense to anyone, but I'm just tired of Chicken Little stories about how old bows are an accident waiting to happen. Yes, they do fail. So do some of the ones from your favorite custom bowyer.
Go ahead and shoot your old bow and just be more careful driving to work right after..... you'll have made your own life a lot safer over all.
