Not to be a pest, but that's a Morane-Saulnier A
I, not A1. Pet peeve of mine. There were three variations of it - the single gun MoS 27.C.1 (which I thought Shaffer's was, but I might be wrong), the twin gun MoS 29.C.1 and the unarmed MoS 30.E.1 trainer. It's always been one of my favorites; I've got an idea I'd like to repaint one of these as Nungesser's post-war F-NUNG someday:
Then again, I have LOTS of ideas.
Carry on.
