|The gas engine is model 7.19 from the 1948 No.7/8 manual
although it goes back much further
appearing in the 1937 no.7 manual. The 1948 instructions were in fact
the same original artwork as those but with the yellow hatched lines
removed from the plates.
Several modifications had to be carried out to complete the model, the
instructions for fitting the cylinder just did not work as described.
It made a nice little project one afternoon
over Christmas 2001. It was a far better model than it looked from the
manual and worked very well when the crank handle was turned. The
colour of the parts is of the Yellow, blue and silver period circa
1970. Many of the parts have been re sprayed to match those colours.
Gas engines often took over the role of horizontal steam engines. They were powered by coal gas (not gasoline) that was piped in most towns in the U.K. The engines quite often drove electricity generating equipment or pumps in water works and often used the same town gas produced by the local council.
