The fingerprint disaster was way overblown...no pun intended. The fault was supposed to be that the fingerprint would change the glass expansion rate at the fingerprint point at power-up and cause the catastrophe. If you thought you had a fingerprint on it, just rub it off. I changed hundreds of lamps in the 70's and no one was impaled. The usual failure was a semi-molten bubble in the glass at a weak spot or a spot that the tungsten line-vibrated to close to that finally gave way.
