Hello everybody
I am mounting an Andaldo SVA.5 from the squadriglia 80.


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 In this picture it seems to be the second one…

Could someone tell me what could be the second propeller brand ?
Thank you
Xan
