As most of us know, SD engines were in Army service during WW2 (and beyond) and used a universal mount that allowed them to be side mounted and fitted to Army FBE's (Folding boat equipment) and also to other small craft as seen in the footage of the army assisting during the hamburg floods.

Alas, still no footage food of a seagull at work during the war, but at some point we will find something.
I've been doing some research and discovered a dated document that shows that testing took place with a Marston FNR engine in 1936. This must have been what eventually led to the later seagull fitted with a sidemount intended for use with FBE's either as bridge pontoons, or bolted together to make rafts and river ferries.
The photos were taken on the river Stour at Christchurch, the location is clearly visible on google maps. The disused dock area is the former home of the Experimental Bridging Unit. I bet Charles SP will know all about this location.
I have ordered some further documents to see where that takes me. It's a slow process but it's all about gathering the facts. Not cheap either as each copied document is £10. That said the scanning is excellent. Hope this is of interest.

Re: Bridge building & SD research
I don't know very much about the Establishment at all, except that it's there and that they did indeed test a Marston - my copy of those documents includes a photo of a gentleman standing holding the engine - he is wearing an absolutely splendid flat hat. Naturally, now the subject is raised I can't lay my hands on the stuff!
Re: Bridge building & SD research
I have the same documents I suspect Charles, yes the guy holding the engine up has a great hat
Re: Bridge building & SD research
Nice bit of research and discovery Adrian.
