2 maybe 4 horizontally opposed cylinder engine - not a Jowett I believe. Whole centre leading edge [and top of windscreen] lifted up for cockpit access. You sat virtually on the floor. I flew one in Ipswich [Straight Corporation]in 1938 several times only because it was cheaper [L1.25 phr] than normal light aircraft [L1.50] in those days. To-day wd probably be called ultralight.

I am interested the engine that was used to power this aircraft. I have been told that a 2 cylinder Jowett engine was used, but have not been able to find any supporting information. Jowett manufactured cars in Bradford from 1910 to 1953.

My father worked for the company that built the Praga in the UK - F Hills and Sons Ltd.
The company built the Praga at Trafford Park, Manchester, under licence from a Czech company. It was a 2-seater sports plane. I'm surprised it is not listed as a Czech plane.
They operated a flying school using Pragas at Barton Aerodrome, Manchester.
One Praga survived until the late 1950's.
