identification of a static engine, (probably ex army)

[Roger Caddick]

Any of you out there any info, specially twin cylinder static engines. I had two of these and made one runner from the pair.
It is clearly embossed with Douglas on the rocker covers, horizontally opposed twin, 4 bolt barrel and head fixings, fuel inlet pipe work is attached to the crankcase with compression/ olive and nut. has external cooling fan and oil pressure gauge. Runs really smoothly.
Alloy crank case. We restore static engines (this our first Douglas) and would be grateful of any information available.
Thank you RC.

Hi Roger,

Perhaps it is a FT35 a 350cc flat twin engine which was probably used as an independent power unit. If you can post of photo or two I may be able to help.

Regards,

Julian
