many countries, UK, and European TVs all ahve some kind of implosion

have a few) make it very clear tht you ahve to fit a separate
implosion screen if you use CRTs without implosion protection.
My issue with saying that implosion was a clear danger was that the
sheet of glass isn't present on all 1940s sets. Could the glass
also have been intended for protection against the soft X-rays
emitted at the CRT face? Remember this was the time when HV
rectifiers and even output tubes were customarily placed in a metal
cage.
