National insignias are the standard ones for A.N.R. (Aeronautica Nazionale Repubblicana) aircraft, i.e. four Italian flags on the fuselage and fin plus two German black crosses. On the wing undersurface, the original German crosses were retained to ease identification from ground. No information is available on upper wing marking but, generally speaking, ANR aircraft had two square fasces markings.
It's also worth noting that by this time in the war metal wing under surfaces were left unpainted in order to save paint and labour.
Based on further research done by Ferdinando D'Amico and posted on 150GCT forum on 06/26/2005 it has been found the following:
- 785xxx series concerned G-14/AS, while 464xxx concerned G-14 manufactured by Erla, often with a larger oil tank used on G-10
- Notes left by Capt.Bellagambi mention two "Yellow 1" aircrafts used inl February 1945: the first wasl W.Nr. 464380, later replaced by W.Nr. 785749
- Consequently it now confirmed that aircraft shown in the pictures is W.Nr. 464380.
It is still not confirmed if there was any sign on wing upper surfaces of the aircraft pictured above. What is known is that some of the BF 109 based in Osoppo (Udine) in early 1945 had ANR fasci other had nothing.
In the end, its just going to be up to you on what goes on top of the wing. Being how there is no photo eveidence, at least not what I have found, it just going to be a guessing game on what is there. Hope the above is of some help.
