Whilst digging around sorting valves for other, thanks guys for ordering, I have found some interesting "valves".
I have used DM70 or DM71 , maybe one of each as one is wire ended, t'other is B8D base. This is the battery set tuning indicator with 1.4v heater and the exclamation mark display.
EA50 diode with B3G base.
Some miniature wire ended thyratrons. 2 types, 22 and 30
and a new boxed PL802/T, the semiconductor substitute for PL802 video output valve which is now very hard to find.
Some of the more unusual items to turn up this week.
