Stuart Turner Identification

Not enough detail in the photo, you need to show more of it if possible.

The url line is broken as well:

The engine number and the plant number would be the best way of identifying the year. Fairways Marine give an exact dating service altho there is a charge unless you are purchasing spares etc they can also if the unit was ever returned for o/haul give you the life history. Mike.H.

I tried being smart by using (at) instead of @ and I guess the newsgroup software outsmarted me.

Lets try again :

There is a plate on the genny - this has Plant number (52254), Genny Number (21975/2) and Switchboard Number (10535) ? I suppose the plant number must be the engine number.

It is plated 230V 1.5 KVA 1500rpm (so I assume its a 2HP engine)

It wasn't that, Steve, it was the line-wrap on your email programme being set too narrow.

IF the plant number corresponds to the engine number, then it would fall into a group issued between Aug 1936 (50000) and Apr 1964 (52269) for P5, P5X, P55 and P5XC engines.

As you say though, it is basically a pre-war design, the P5 engine being introduced around 1930.

There should be an ID plate somewhere on the engine your pics do not give enough detail but there seems to be something akin to a plate on the casing below the carb. if you can find this number it will allow an approx. dating Mike.H.

I am pretty sure the plant number must be the engine number, after all the alternator and the switchboard have numbers on the plate, and there is precious little else left but the engine - unless 'plant' refers to the entire ensemble. There is no sign of a plate on the engine, or even a location that used to have a plate. So it looks like it is a late P5 genset. Any idea of the differences between P5, P5X and P5XC ?

I'm fairly sure the P5X engines were those used on aircraft refuelling bowsers and, if it follows the usual S-T nomenclature, the P5XC would have had a centrifugal clutch. The P55 is a twin cylinder version. By the way, given that demand for the non marine P5 would have been pretty low towards the end of that period, those last few numbers could have taken some time to 'use up', so you could be looking at late 1950's - all provisional of course on the assumption that the plant number is the same as the engine number.

Thanks Nick,

I I find any other numbers then I'll let you guys know.

So what goes on in the big lump cast onto the side of the cylinder from which the exhaust emerges ? It looks a fairly straightforward 2- stroke apart from that bit - it has me intrigued.

Nothing very exiting - it's a water jacketed exhaust expansion chamber

Lister and many others used the Plant No for the whole assembly, not just the engine.
