An enclosed high speed twin engine, the Sirius was introduced in 1928 and remains in production to this day, finding use in diverse applications from generating sets for charging radios to racing hydroplanes.
We've had many of these - and the smaller "Sun" from which it was derived - over the years, including a particularly nice one way back in 2001.
There is an interesting history of the engine on the excellent "Stuart Turner Steam" website here.
