Yep, REL1, aka VT90 (British VT numbering), 710A, 8011, the original
micropup triode used in pulse mode in pairs in WWII radar transmitters. A
pair could deliver a 10kW pulse at 300MHz and would go to 600MHz I believe.

They don't fetch much money unfortunately although yours is a REL1 so
someone with the VT90 marked one might want to add this as well. The REL1
itself would have been made by Northern Electric for REL (Research
Enterprises Limited).
