Sorry it was the Fiat A.S.1 trainer
I must have had double vision I could have sworn the picture was of a bi-plane and of course it was a mono-plane.
The 35 could be the aircraft’s number. I’ve believe fighters and bombers usually had the squadron number on the fuselage and I’ve seen some pictures that had another number after it that may well be the individual aircraft number and there is something before the 35 [11 perhaps].
If you can’t find a forum the specifically deals with the Regia Aeronautica can I suggest this one at http://www.stormomagazine.com/index.htm
, may be able to help, these modelling people are sticklers for authentic details.
Apologies once again for telling you the wrong aircraft type.
