CMASA J.S.54 flying boat

[hesham]

Hi,

we spoke about some little known aircraft of this company,such as
CS.15 and CS.38,also the BS.12 four engined seaplane project,the
company also developed the J.S.54 six-engined civil flying boat,but
it was never produced.

Yep, in 1937. I have two photos of the duralluminium model. I'll scan and post.

Can anyone confirm whether the 'J.S.' prefix was actually a stylized 'I.S.' for Idro Stiavelli?

Hello!

Picture from above motioned ALA magazine from 1948.
Perhaps this is J.S.54 mock-up (picture above)?

 

[hesham]
