To complete the survey the bottom bracket would have to come apart to look at the axle markings! The differences are pretty small, so don't panic - it no doubt rides perfectly well!
Wow, I'm starting to understand why Sherlock Holmes originates from the UK
I've just checked the cranks: on the back they say '170 STRADA'. On the pedal mount is written '9/16 x 20F' but that's refering to the pedal axle size I pressume?
