Hello,
Possibly still on ebay is a photo of a Savoia Marchetti S.M79 of 281 Squadriglia at:
https://www.ebay.it/itm/304286737610...EAAOSwTUlh0won
I'm not certain that there is anything significant about this aircraft,but the sale has ended within hours of being posted,so possibly the photo is significant.
Edit
On 04.01.22 photo on ebay again,so presumably not significant at all.
Regards,
Clint
