I agree with the DO NOT SHOOT IT recommendations. In addition to delamination, which should have been an obvious concern at the time of design due to differential in expansion with heat and cold and heat transference between aluminum and wood laminations, the other , much bigger, risk is that aluminum , especially the alloys available back in the 50's, has a very rapid stress-cycle deterioration to end-of-life failure. The Grimes and other bows made with solid aluminum limbs simply blew apart under stress after far fewer cycles ( drawing and releasing the bowstring) than wood or fiberglass bows , then and now. Grimes switched to take-apart bows with aluminum handles and solid fiberglass limbs, and that was the model for metal-risered bows from the mid-50's right up to today. But aluminum in the limbs was a recipe for disaster. They were noisy as all get-out, too.
