Hey Rafael !!
The AZUR kit is the only plastic kit that I know of. There are some vacu-form kits, though.
You may have to scratch build the version you're looking for.
There is a good book on this plane, it's: Breda Ba.65 by Giancarlo Garello.
Other than the 1/2 seat versions, there are also 2 engine variants.
The K.14 and P.XI. The K.14, which the AZUR kit depicts, is an Issotta Fraschini engine and P.XI is made by Piaggio. The cowlings are the only visual differences.
Well, hope this helps a little,
Take care,
DeP
