Unknown Spark Ignition 2 Stroke

Can anyone identify this engine for me please,

It's a 2 stroke spark ignition single, fairly crude castings and machining so may have been from a casting kit,

There are no fittings for a contact breaker outfit, but has a machined slot in the nose and clearance for a cam and push rod,

Alloy head, cast iron cylinder, approx 3/4" bore & 1" Stroke, overhung crankpin and a bronze connecting rod, the piston looks a bit skewed with the deflector on the crown hand filed, intake on the back of the cylinder with exhaust through slot drilled & filed in the cylinder casting, carb's missing unfortunately,

Total height approx 3.3/4"crankcase back to front of nose approx 3", crankcase approx 1.5/8"

Few more photo's:

Looks like a pre war Slag engine from the USA. It looks very familiar, I will try and put a name to it.

Thanks Andrew, much appreciated, I've trawled all over the web and found nothing like it,

By the look at the end of the crank it has ploughed into the dirt fairly heavily !

It's possible, but the machining is off centre slightly which makes it look odd, and by the look of it someone has chewed the threads off with mole grips or stripped the threads winding something off the end brutalising it, appears threaded off centre too,

Haven't had the crank out yet because of the shape of it, so no idea what other horrors lay in wait.
