Anybody know what it is?

I believe it is an early G-Mark engine made in Japan. I think it was distributed by Cannon R/C in the 90's along with the .03 engine, sadly both companys are gone. I bought one on E-bay awhile back and would certainly like any more info on it to.

Looks like a prototype as there are lots of differences in the production models but it definitely is a G mark.

Hi,
Think you may have it right, certainly says made in Japan on it, the only logo is on the back plate.
The letter M with an arrow above it. Too small to see on my rather poor photos.
Is this the logo on yours?
Will try and post another two photos.
The part I can't figure is the copper strip running round the back of the cylinder and going
into cylinder block. What is it for?

Unfortunately no, its not my engine and I don't have access to it at the moment.

Thanks guys for correctly identifying it, much appreciated.

Its an early version of the G-mark .061(quite rare), the latter model had a different muffler. Here are some comments from RCG:

G-Mark .061 (1.0 cm³)

Manufactured in 1980

This engine uses a nice cast crankcase and a steel cylinder. These cylinders were also used for a flat twin and a 5 cylinder radial. The G-Mark company also produced a larger .15 single and a .30 flat twin, again using some identical parts. All G-Mark engines were well designed, but probably too expensive to manufacture. I have flown this engine in a small Piper J-3 Cub.
They had a nice .12 twin based on the same engine and a 5 cylinders radial (.30):
