Ruston Hornsby 6X class H engine starting and running

30h.p 6XH Ruston diesel engine from 1925. This engine spent 30 years in a park and it has taken me 2 1/2 years to restore it back to running condition again. It is being started on 200psi of air which is pumped up by the compressor and small engine at the back. This size was the largest Ruston that came with a set of crank handles!
