Many thanks to Martin Dasek of the Czech Republic for these pictures taken at the Czech National Technic Museum in Prague.   This machine was originally built in 1939 by G W Patchett with a twin cylinder, 47hp OHV engine, but was never tested due to the outbreak of war.  It was later rebuilt by Sklenar as a double overhead cam machine and subsequently supercharged.

Sklenar also designed his own DOHC twin supercharged machine, that later had the supercharger removed.
