From the junk box - can anyone identify it?
No markings other than those shown.

Buttafucco Stunt .60

I developed this motor back in the fifties.

The rear-rotary valve says the designer wanted high performance.  Yet it appears to be a loop-scavenged engine, with plain bearings.

I have no clue what it is, but it looks like it's from the fifties or early sixties.  If it was meant for high performance much after that, it'd have Schnuerle porting, and certainly doesn't seem to.

   It looks a lot like a McCoy 60 with the head fins shaved to fit in a cowl.

Brodbeck?  Pre-K&B

The engine was removed from a magnesium speed pan. It has dual ball bearings and is loop scavenged.
The intake timing is quite radical.
There is no spray bar so it must run on pressure. It was set up in the pan for crankcase pressure.

Looks like some one has filed on the exhaust ports.

Looks like something that Bill Wisnewski had a hand in designing. He worked for K & B from the late 40's or 50's until 70's sometime. Was a member of the great TWA speed team.  Kenny Two Flights

Looks like a Hungarian hybrid of the McCoy and Dooling.

If you're really curious, go through the site at http://www.modelenginenews.org/.  They have an "engine finder" page, but it's indexed by name, not by engine feature, so you'd have to dig to see if they have one.

The author also collects "whatzits", and tries to identify them.  He may be interested in your pic -- or you can plow through his pages of watzits, and see if you see the engine.

Well, it's a homemade .60 speed engine. Since it was found on the East Coast, I'd send an inquirey to George Brown (B)...Long Island, NY, I think. His son is in Phoenix, AZ, and flying speed 'round there. Put the pictures on the speed forum here at Stunt Hanger and ask that they be circulated around to likely suspects ("B's"). Joey's a good dude, and he'll help, I bet. Pretty cool engine. 

We found this engine in the collection of RF Stevenson. I think it was locally made in the PNW. I recall a guy showing up with a homebrew engine at a speed contest, and that Ed Fisher ran or flew one a bit. I think the guy's name was Kumar or something like that. Also cool...  Steve
