[amsat-bb] Identify AO-51 Payload

In that famous photo of the entire payload of satellites that included AO-51 (where AO-51 is at about at the 6:30 position - with that largee Italian engineering bird to its left), there's another satellite at about 02:30 that looks exactly like AO-51 (size and visible panels are alike).

Whose satellite is that?
