Thanks for that. Worth a try.

Cheers!

It's an interesting engine with all those brass plugs on top.

Access to the valves and adaptors for the plugs?

I am intrigued by the crankcase which appears to have space for another pair of cam followers.

The plugs are to access the valves which are typical of a fixed-head engine. The Thorny and the Dennis are the same. The centre plugs must be a simpler way of sealing off the water jacket instead of a flanged cover with studs.

You are right, the apparent spare follower positions are intriguing. To someone who knows what the engine is, they will be the main clue!

It is amazing what is about even 100 years later.

If you look behind the cam followers it seems that it has a 2 cylindre casting.

Yes, it is a two-cylinder engine but with a tee head so you would only expect two followers per side.

Hi, Steve.

Thunderbolt and lightning (very very frightening) here, so spending a few moments indoors. Might your mystery engine be a Georges Richard. I have some more photographs somewhere, but can't lay my hands on them just now. In the meantime, this will have to suffice. It's something I found online a while ago when I was looking for engines suitable for the 1906 Barford and Perkins C/C2 roller. Not identical, but the shape of the timing case caught my eye. So far as the spare tappet covers are concerned: might these hide cams for the trip gear of a low-tension ignition system? It is the inlet side of the engine - where igniters are typically located.

Hi Andy. That is remarkably similar. Thanks for that.

This Unic engine is different in detail, but does hint at the possible purpose of the extra cam follower holes.

Though actually I don't know what those extra levers do. I did think possibly low-tension sparkers ("long mingling spark") but there are (maybe conventional) spark plugs. Albeit with weird HT connectors and possibly some levers.

Assuming there is no magneto, maybe it has something like a trembler coil and those rods that appear to be activated by the camshaft are operating the rods that link to the spark plugs,  therefore acting as a distributor, make and breaking at the plugs?

An intriguing early trailer for sale.  Probably not military but interesting nevertheless.  Why don't they show a picture of the name/data plate!?

Looks like carrier wheels, post ww2?

Ah yes!  I was imagining something on a very different scale.

Not sure whether these are WW1, I think later. Anyone ever heard of the 'Truck and Tractor Appliance'? This is the only link I can find on the www: https://www.britainfromabove.org.uk/en/image/EPW034851

My friend took the pictures last week, he thinks it is a front (steering) axle. 

Thanks

Marcel
