I'm sure there's plenty more to be found on the subject.
Way back in 1986 when I was shepherding a pre-war EMI 12" CRT through a rebuild we had a choice of several dead ones. We chose on the basis of which glassware had the fewest visible defects and hence lowest implosion risk. Here's that pyrex CRT with Charlie Bradley, the glassblower at Display Electronics in Uxbridge. The gun has been removed and the tube temporarily sealed off. The gun is on the bench between the 2 CRTs.
