I know Twin Stack is always coming up with "mystery engines" so I thought I would post, sort of, a mystery engine example too.

This one doesn't show up in the AMEE book either.

It does have "Old Timer 032" on the cylinder side (rear) though.

It's a Shilen .19 otherwise known as the Old Timer. Though a new design, it was approved as an original ignition engine for SAM competition.
Ed Shilen was a master gunsmith who produced the DGA (darn good action) for bench rest shooting.

Trying to be positive... the entire bottom end looks recoverable...

Edit: Thinking again about this poor Brown, it occurred to me that maybe some idiot wanted to make a .60 CO2 engine...

Yeah it looks like someone wanted a large carbide engine (Co2). They used the big carbide engines way back in the early 1900's. They were fairly popular at the time too.

I don't feel so bad about my soldering now.

What is really interesting is that it likely worked pretty good actually. I could see someone using it in a boat or car. But it might have been a school project to make something like that.

Decided to build my own ignition treasure today . I have wanted to use spark and petrol on a 4stroke in Texaco ,so I set one of my OS 61fs up with a cam shaft driven cam for the points . A 5lb 9oz model will give me 12 cc of petrol , on a 16x7 prop , should get about 3.5 minutes engine run at 5000 rpm and plenty of height .

Yes, the engine is like your pic of Rojo collection. I saw also on eBay the instruction manual of "Ken .610 Racing" engine, maybe there are two or more models of this engine? Thank you!

I've shown this one some time ago. Could not resist opening it up so here are the pictures. Just made a new heat resitant gasket for the cylinderhead. Very well made engine but coming out in 1947 with Ray Arden on the tail... and of course the design was obsolete by then. Baffle on the piston ? Looks like a chromed piston and no ring. For those un familiar : the Howie&Heuer from 1947 and considered the very first commercial glowplug engine. Took me some 30 years to find one......
