I'd lean towards it being a STH-10A. The motor looks like the typical 3 phase one with the eyebolt sticking out of the top. The Banshee 110 doesn't have an intake like that; they actually don't have one at all unless it has a damper, and even then it's not built like this. The OM-120's motor wouldn't be exposed like that either. Its horns were probably destroyed at one point and they put a skirt on it.

No, I don't think a dual-toned STH-10 was ever made.

STH=single toned high. The 2/3T22 was basically the dual toned version.

The xT22 used the smaller rotors from the Model 3, not the larger ones like the STH-10 and STL-10.

Too small to be a Model 3. Likely a Model 2.

Oh now I see. I swear I there was a post of a model 2 with only 2 louvres at the top like this in the off topic forum somewhere.

It's a Model 1 missing the bottom louver.
