ID this instrument?

Thanks Fly Buy
I have no ebay account, and it’s surplus to requirements. Available to anyone who might need it for a cockpit restoration.

Rate of Climb indicator, standard fit to most post war British military aircraft from the mid 1950’s to 1980’s. Found on anything from Canberra’s, Vulcan, Victor, Vampire, etc etc…………Fighter, bombers and transports.

Thanks Kernowglyn
Any particular A/C it was fitted to, or a standard instrument for several types?. I take it that it is post war.

Looks like the standard RCDI, but the ones I remember also had the word Down on the lower half to match UP on the top half.
Rate of Climb & Descent Indicator, often known as a Vertical Speed Indicator (VSI).
