I have two O'scope crts (3BP1 and a 2AP1) that are still good (they were
purchased as military surplus when I was a teen for homebrew use) and
neither were made much later than 1958 (maybe much older!). I know they
work as the scopes I built with them still operate! The glass
doesn't decay. If the phosphor is peeling it may be that someone has
vented the tube to remove the implosion hazard.
