Hey Alan, I'm thinking it's a Chunn, which I know nothing about.

never seen anything like that before,i wonder how much horsepower that put out and rpms

Found this(Model Engine News):
The original engines, bare, weighed in at over 12 ounces. The single MAN advertisement quoted 1/2 a horse power with a total flying weight of 18 oz including coil and batteries. Reference [1] suggests it turned a 14-8 prop at 5,000 rpm. The Fadden reproduction engines described below are quoted as turning a 10-6 at 5,600 rpm. In-line twins are great fun, and as I found out with my Prototype Taplin Twin repro, as they sound like they are going twice as fast because you are getting two bangs per rev.

very friggen cool

According to the link, the Chunn is only a .32.

The cylinder on the engine he's holding looks familiar/typical 30's practice: screw on transfer. Maybe he built the engine using some available parts. Seems like he was a talented guy: check out those parts to the right of the Forster 29. Alien technology?
