Silhouette challenge

[SincoTC]

Good evening one11,

I think the engine may be a Menasco and wonder if it's a Swallow C Coupe ?

I have found a photo on Aerofiles, it's taken from a slightly different angle, but it seems to fit fairly well.

Please declare Open House if correct, as I have to be off in a few minutes and haven't had time to get the answer/clues together for my next one fo send to LM. It looks as if I've missed a couple of interesting days!!
