Identification of Aero Engine Casting.

[Fluffy]

G'Day All,
I was recently given a box containing six unmachined aero engine castings. Five of which had a set of detailed drawings. The one shown below has no drawings & I cannot identify it.
Can anyone who is into model aero engines/planes, ID this engine. I am pretty sure that it is a two stroke, glow plug engine as the casting has a transfer port in that would be sealed by the cylinder.
Thanks in advance.
Don.

You casting is for a 10cc glowplug Titan 60 designed by George Genevro. It was designed as an engine for home construction and the designer sold the plans and the casting. If all else fails Eric Offen (a member here) has a copy of the drawings and also possibly a casting. I know this because he bought them from me.
