This is a Russian Yak11 Tachometer. It is in pretty good condition and a worthy addition to the collection of any fan of Russian warbirds. The Yak11 itself was a derivation of the mighty Yak3, a plane arguably more feared by the Germans than the British Spitfire and the only plane that we have ever heard of being mentioned in German dispatches at one point as not to be engaged by fighter pilots if it could be avoided.
We also have another one of these tachometers complete with the engine speed sending unit.
