C.M.A.S.A. - Construzioni Mecchaniche Aeronautiche SA Designations

Rinaldo Piaggio began SCMP (sometimes 'SDCMP' for Societa di Costruzioni Meccaniche di Pisa) in 1922 to license Dornier designs. In 1929, SCMP joined the Fiat Group and, in 930, the name was changed to Construzioni Mecchaniche Aeronautiche SA aka CMASA di Marina or simply 'Marina Fiat'.

The first designations are listed as MF for 'Marina Fiat'. The CMASA-built Do J Wal is listed at the MF.5 but the earliest numbers are missing. I am posulating that these umbers were used internally to designate licenced Dornier designs. But which ones?

Other than the Do J Wal, the Dornier designs built at Marina di Pisa are said to include the H Falke (1 x conv to Seefalke), Do E, Delphin, and Do O 'Expeditionary Wal' (online sources also list CMASA-built Do Fs but that seem improbable). So, although it is a stretch, we have four Dornier types built at Marina di Pisa and four missing MF designations.

If anyone has access to Sviluppo e attivita della C.M.A.S.A by ing. Guido Guidi, this may solve the missing designations mystery.

The MF series of designations was replaced by a new CMASA system more in the Italian style listing role and designer's name. Designs originating with the parent Fiat firm but produced at Marina di Pisa did not receive new CMASA designations.

Thanks Hesham, that was my sense too. But was one a derivative of the other. Or is BS a typographical error for JS? :eek:

Thanks Hesham. Something rather obvious occurred to me reading that. Italian journals of that period often used a fancy, 'J'-like display character for capital 'I'. That mysterious 'JS.12' is more likely to be the IS-12 (for Idro Stiavelli).

Hello, my idea of how the SN16 should have been.
Cheers,
Marco

I do not speak Italian so I only want to notice another explanation of the abbreviation B.G.A. :

" In 1937, FIAT C.M.A.S.A. built the prototype of a twin engined bomber landplane called B.G.A (Fig. 3). Its name stands for “Bombardiere Genio Aeronautico” (Air Force Engineering Corps bomber) since General Aldo Guglielmetti was one of its designers. This monoplane was based on the same specifications that gave origin to the FIAT BR20 Cicogna, which won the contest, although it was somewhat structurally heavier than the B.G.A. ".

That could not surely be right of course, and comes from the site https://www.researchgate.net/publication/273455013_Forgotten_aircraft_the_aeroplanes_of_CMASA

Hi Boogey,
I ever read BGA for Bombardiere Grande Autonomia (long range bomber) and I thought that designation was fair consistent with Italian use.

I think those aircraft projects were two different types as the JS had to be a six engined passenger flying boat, project was abandoned,
and the BS.12 design had to be a four 1000 hp Piaggio engined bomber and reconnaissance flying boat and was rejected as too costly.

It's the link I placed already in my earlier post :
https://www.researchgate.net/publication/273455013_Forgotten_aircraft_the_aeroplanes_of_CMASA

The type designation JS appears without numerical part ( .12 ) there.

So what do we know about the JS.12 design ? It's a pity there wasn't any information that designation J.S. in the article refers to the JS.54 what confused me.
Reading it I was sure that the description of the six engined passenger flying boat concerns JS.12.

My dear Boogey,
