It's a National DM2, built by the National Gas & Oil Engine Co of Ashton-under-Lyne. They later became part of Mirrlees National, I suppose what remains is now part of MAN.
They were built under license from Russell Newbery, initially because RN were offered a contract for more units than they could handle for a new fleet of Narrow Boats for the Grand Union Canal Carrying Co. in 1933. RN (well, their successors, at one time they were owned by the makers of Sterling machine guns) still make them in very small numbers, some history here:-

This is a 2-cylinder, 18 bhp @ 1000 rpm, hand start only, they were built in 2- 3- & 4-cylinder versions mainly for generators or marine propulsion. Nationals made them for a number of years, as well as a scaled-up version, and then developed their own variant with conventional overhead valves.
