ROLLS ROYCE KESTREL V-12 ENGINE

The engine was first produced in 1927 at 450hp (340kW), which soon improved in the IB version to 525hp (390kW).  This variant saw widespread use in the Hawker Hart family that was the mainstay of British air power during the early 1930s.  However it was not long before line improvements increased power dramatically and the V-12 model provided 695hp (520kW) at 3 000 rpm with no basic change to the design.

WALTER MINOR 4-111 FOUR CYLINDER IN-LINE AIR COOLED ENGINE

Manufactured in Czechoslovakia (now known as the Czech Republic) by the Walter Company after World War Two, this piston engine powered the Aero Vodochody Aero 45 twin engine civil utility aircraft.  It was the first product of the nation's post-war aviation industry and proved a great success with many of the 590 aircraft produced being exported.  The engine on display still remains in its most unusual original hand-carry wooden cradle.
