Does anyone recognise this model engine?

I finally have better credentials for reading 'model engineer' but only as a collector. I bought this…

Pretty sure it is an engine. It has inlet an exhaust and a suggestion of a fuel pipe/carb so I guess it was intended to be IC.

I think it has twin 'cylinders' (I bet they are flat, not cylindrical) that move towards each other on an arc with a single combustion chamber in between.

I also guess it is 4 stroke as there is some backgear and cam which means the 2 valves each operate on alternate rotations.

I don't expect it would ever work… the concept would seem to require accuracy and precision well beyond that which the evidence of build quality would suggest has been achieved. But somone has invested a lot of thought and time into making it.

my guess is it runs on air or vacuum it reminds me of the vacuum motors fitted to old cars

Very Interesting

Looks like a labour of love by an amateur

Air pressure may get it going

As above plus keep your fingers well away because it looks like everything moves !
