Back again Ken,
I wasn't entirely convinced about the Alpha, so I just had to have another look!
I found this photo that rather looks like the one you used:
Photo Unknown Robin HR.100/210D Safari D-EHPL
the caption says it's a
Robin HR.100/210D Safari
But then again, the photo of the Ambrosini I found after LM posted, was your picture, but the Italian website captioned it as an Ambrosini F4 Rondone, I should have zoomed in as it had F-7 painted on the cowling!!
Really off now so OH please if it's correct this time!
