USAAF/USAF C79

Do any readers know if there are any photos of the “C79” used by US forces. I believe that there was only one so the C designation may be unofficial. The aircraft was a Ju52.
The reason for this is that I would like my latest model to raise a few eyebrows at the next show.daimargs@optusnet.com.au

Haven’t been able to find any pictures. The a/c was used by the 20th Troop Carrier Squadron during 1942. I believe they were stationed in the Canal Zone at the time. It was a one off war prize, I think from Bolivia, used for a year and then passed on to Costa Rica. Doubt if there are many pictures.
