Hello Vincent.
thank you for your nice message, I'm a beginner and it's good to get good feedback from a "senior" !!
I don't know if this n.10 was the personal machine of Annoni or Lucchini.
For sure they used this kind of machine in 4° Stormo.
Lucchini was probably using a 90-2 as you ca read on his biography written by Flavio Silvestri on this link

My next model will be a IMAM RO57 Special Hobby 1/48, I will post some pics of the work in progress.
ciao a tutti
Massimo
