Anyone know what this bad boy is? If there were markings, they have been ground off. It has phenomenal compression. TIA #^

It looks like a 1950 R-B Special - .299 glow engine.

Did they come from the factory milled flat like that, or should we suspect that someone's fuselage was just a bit narrow?

Would the shaft out of the back be indicative that it had been made for spark?

RB Special - a quality engine in its time. Held the U.S. 29 speed record at one time(?) Gave the McCoys a run for their money.
To me, the top half never seems to match the bottom half. The bottom half looks rather a rough casting. The top half more precise, with some precision engraved writing on it. You can just see what's left of some writing on the bypass. A hint of R or B and the beginning of "special".

All of the R-B engines had the crankshaft coming out the back.
the 1946 R-B Special .29 was an ignition engine with the name on the bypass.
The 1947 R-B "C" was an ignition stroked .29 which had a displacement of .362. No markings on bypass.
The 1950 R-B special was a .299 displacement glow engine. It still had the shaft coming out the back, but the back cover was not drilled for a timer screw and the rear shaft housing was not cut out for points. Name on bypass.
Aren't you sorry you asked?

I have always said and I will say it again, If De doesn't know about, it probably never happened. You always amaze me about this stuff De.

Hi Jim,
I have a book named the American Model Engine Encyclopedia by Tim Dannels. That's why I sound like I know all this stuff!

R-B Special.

Thanks for the help ya'll, pretty interesting! If anyone would like this motor, drop me a pm w/ an offer. I'd love to see someone on here get it, instead of going to ebay.
