Hi Mike!
Your Balilla is a beauty!
Two news from the real one: the double rigging wires have an internal wooden "soul" held together with the cables with linen clamps. Wire/wood/wire have an oval section. When I reproduced them in 1/72 scale I used some white glue to fill the space between the cables and give them the right and pot-bellied look.
Windscreen had a wooden structure, not metal. I remember well because the one of 16553 was broken when we took out the plane from the Rock of Bergamo.
Hope I'm not in late, if yes I'm sorry.
You're near to the end!
Regards,
Roberto
