Thanks Hesham. I can now confirm at least one flying boat type built by Gallinari.
There is mention of the Società Anonima Industrie Meccaniche Gallinari holding a licence to build the Anglo-French FBA Tipo H flying boat in Italy. That right is usually associate with the Societa Idrovolanti Alta Italia. Of course, SIAI also devised a Tipo H replacement in the form of their S.8 recce flying boat of 1917.
According to
Progettazione e produttività dell'industria aeronautica italiana dalle origini al 1943: Le relazioni della "Direzione Costruzioni Aeronautiche" dell'Aeronautica Militare, Gallinari built 93 aircraft, primarily SIAI S.8 flying boats.
"... Azienda - Società Aeronautica Italiana Gallinari (Livorno)
Idrovolanti - 93 (modelli vari, principalmente S.8) ..."

There may be some confusion here. According to forum member
aviostoria, S.8 production was by CIVES of Varazze and Società Anonima Ducrot of Palermo. There is no mention of Gallinari.

On the other hand, SIAI, CIVES, Ducrot, Gallinari, IAM (Naples), and Zari (Bovisio) all participated in Tipo H production. So, we can say '
sì' for the FBA Tipo H and '
probabilmente' for the SIAI S.8 being built by the Società Anonima Industrie Meccaniche Gallinari
