I must admit I am very young at this trade. I am 67.
I dont even know, nor have I seen a "Rimlock" valve.
Very often there are valves with designations such as
ECH,
EBC,
EBF,

prefixes.
I then load R-Type.org to find out what they really are.
( MOSTLY I look at the alternatives)
I have never been to New Zealand, even though its only "over the ditch". I do know that about 1/2 the RAF migrated to NZ after the war, and designed some excellent radios and TV's before we went colour TV in the 70's. ( We never had TV at home)
In the whole of my career and education, Australia has only ever used USA designations for valves.
Noval base is immediately recognised as 9 pin miniature.
Octal is of course original 8 pin with spigot
Miniature is 7 pin miniature, which I am 3/4 sure made huge headway in Australian manufacture during the 1950's.
Loctal I know from African military radio gear that was sold into the surplus market in the late 1950's and early 1960's.
Also, I have discovered that the Australian military used many types of loctal valves in the early plywood jet aeroplanes.
These are plentiful here, BUT still use American numbers, not some hidden code of secret numbers and letters that mean ( after 60 years of working with valves) NOTHING.

I dont mean to be disrespectful, but surely there is a common thread here??. Would it be possible to list BOTH type numbers in posts?
