Found this quick reference in a long and interesting inteview to Italian ace Luigi Gorrini, talking about his war from 1940 to 1945.
It seems there was another pilot who was riding a captured P38
D. Quindi a difendere Roma non c'erano che una sessantina di aerei?
R. Sė, c'eravamo solo noi con in pių qualche aereo della notturna a Centocelle, ma poca roba. C'era Rotondi che volava con un Lighting che era stato catturato agli Americani e momenti lo buttavo gių io, sta testa di cavolo...
[about defense of Rome, 1943]
Q. So in defense of Rome there was only about sixty airplanes?
A. Yes, there was only us [III Stormo, with Macchi 202 and some Bf109]plus some nightfighter in Centocelle, but very few. There was Rotondi who was flying with a captured Lightning, and I nearly shot him down, that ******* of a guy... [note: 'testa di cavolo' can be translated with '*******', but is to be intented in a friendly and sympathetic view]
Full interview is here, for those who understand Italian (maybe if somebody is interested I could translate it in a lonely dark night..)
