These are prototypes designed for high
pressure, high flow operation. The
rotors are intricately machined
from solid alloy bronze and must
have taken quite a bit of work to
complete. The spare boiler
I keep around here is able
to produce up to 25 PSI which would
turn the turbines at very low RPM.
When hooked to an air compressor
at 40 PSI the turbines operated
I'm told they were made in about
1976 as part of a course study by an apprentice at The Royal Armament Research
& Development Establishment which is part of the British Military, located
in Seven Oaks, Kent England.
