Searching informations about Italian Props (for Ansaldo SVA.5)

[Xan]

Hello,
I am searching information about Italian props , and more precisely about Ansaldo SVA.5 propellers.
I founded SVA.5 had SFA 6 engine, ut I didn’t find anything about italian propellers
Windsock datafile proposes two propellers models:

The first one seems to be a bolt propeller:



But propellers I am searching seems to be the second one…





So I am interested by any informations about Italian props:

1) What could be the second propellers brand ?
2) Which were the Italians propellers brands or firm ?
3) Was Bolt an italian firm ?
4) I think there was Turbo propellers too ?

Thank you

I have also done a little bit of research into Italian propellers and have not been able to find much. Interestingly this article has a picture showing bands on the propeller of an SVA9. That might help in identifying the manufacturer:

Also, there are some photos claiming to be SVA propellers here:
