This was posted on a couple of websites quite some time ago. and I identified it as a Aichi E13A Jake floatplane (sans floats). The “panel” holes are misleading as are the missing wintips and more info as to the site has appeared on the web in recent times.
I think this might be a tad difficult and it had two manufacturers in two countries and at least two different engines. One visited the UK in the 1950’s.
Meridonali obtained the licence to produce Fokker a/c in 1925. These included the C.V and the Trimotor FVII3m. The designation Ro for Romeo was carried by the entire series.
Apart from that the Ro.1 was a Jupiter engined C.V.
