My opinion is the bows were pretty good back then.If you were to shoot full size arrows I think they would have stayed together. That long ago a lot of bows were blowing limbs(overdraws) due to pushing them to extremes trying to get speed out of them. I remember bows that required 6 ounces per pound or they would void warrenty. Most people were bordering 5 grains per pound to get speed for 3D shoots and with shorter & lighter arrows it was like dry fireing the bow with the outcome of blowing a limb.
