Pensuti 2

This little triplane is by a lot of people known as the Caproni-Pensuti.
I have a question concerning the height of this aeroplane.
In Jane 1919 and Flight of that period the height is mentioned as 2,40 m.
After the death of Pensuti its project was sold by its family to Breda.
In an article concerning the Breda-Pensuties there they mention that the height was 2,90 m.
This is a big difference with such a small aeroplane.
Also on a postcard of that period the height is mentiod as 2,90 m, see enclosed.
On the internet I found a drawing of the Pensuti 2 which has a height of 2,80 m, see enclosed.
Knows some one, or has some one this article where this drawings was showed?

Who can help me with more information concerning the height of the Pensuti 2?

Thanks
Jan
