Hi Stig,
Just curious really about the bet my head saying, we of course have the same functional equivalent with the use of sticking my neck out, but then we too have a related cultural heritage.
Anyway about 1260, it was a number used for a french MF.11 I would think, I see from
http://albindenis.free.fr/Site_escad...ete_Farman.htm 1259 and 1263 were in any event. Still, as you say french machines had the number on the tail, so not I would suppose a french machine operating in Italy, which at one stage crossed my mind as the number as you rightly say is on the body of the aircraft. I tend to agree with you not a SFA number.Hopefully more will emerge...
Regards,
Clint
