[WWI] chiribiri?

[iban]

ok, i realize this is slightly pre-topic, but i've looked all over and 
only managed to find one reference, so i'm asking you folks.  i know, i 
know, i should have asked here first.

antonio chiribiri built a series of 5 aircraft in turin, italia, between 
1911 and 1913.  i'm looking for info on all of them, and particularly on 
number 5, the last and best.

i've found one drawing and tiny 3-view in rand-mcnally's world aircraft: 
origins--wwi (of all places!) and not a single thing anywhere else.

the guy was apparently a pretty good designer, because the web throws 
back lots of post-war car designs associated with the likes of 
pininfarina(sp?), lotus, and ferrari, but not a single aeroplane.

do any of you know anything about this guy and his aircraft?  i'm 
especially looking for reference photos and good multi-view drawings, if 
they're out there.

thanks in advance for any help, and slava, welcome to the list!  for 
people who love old aeroplanes, this is the best, funnest, and most 
informative group of people you could possibly choose to hang out with.  
which is why we keep putting up with each other!  :)

cheers,

iban.
