There's a longish article by Pinotti, here are two tidbits:There is no specific mention of where the UFO was when alleged recovered by the OSS (post #108) in 1944, however.
Unfortunately, an original thirty-page dossier about VNC (i.e. the one that had been sent to the newspaper IL RESTO DEL CARLINO of Bologna) was lost, while the first batch of photocopied material sent to UFO: LA VISITA EXTRATERRESTRE did not have the result “Mr. X” had desired. This magazine entrusted their enquiry to the Naples ufologist Umberto Telarico who was skeptic about the case. The material got published, but they considered it a fake.
In April of 1945, the 1st Armoured Division captured the SIAI Marchetti Aviation Facility where the 1933 Magenta UFO (or it debris) was probably kept and it was brought to the United States.
