Not directly applicable to the VHF64 but I came across a few NOS valves yesterday - all Mullard, even if one was in a (correctly marked) Mazda box!
Two of them were PCL85/805 but one looked rather odd. It was in Kradlepak, with the trademark, type number, etc. marking face upwards but there were two things I noticed: one was the font used for the type number looked wrong and there was a strange symbol:└┘ on it.
When I inspected it in more detail, the pentode anode was black, rather than the usual dark grey colour and there was no batch/date code etched into the glass. It was clearly marked, though, as made in Great Britain.
Obviously a buy-in but who was the original manufacturer? Another PCL85/805 was perfectly normal in all respects, including the Blackburn date code.
