The SM75, entered in service in 1938, was pretty much a "modern" (among quotes) plane, and a STOL one too (the first, shorter ones). In fact, if you remember, I had raised doubts about the P108, so it's reasonable that the 75's props could be the more modern and efficient ones, especially seen the performances it had to have...
I guess I involuntarily expressed myself in an ambiguous way, the trimotors I was talking about were the older ones, like the SM79 Gobbo Maledetto like the one I saw in the Museo Storico dell'Aeronautica in Vigna di Valle, and about which, at my technical question (that had other people, and even the guide, looking at me like I was speaking about Quantum Physics in the Kansai Japanese dialect) I had, after a while (after they asked around, as few people make those kind of in-depth questions about planes' mechanics there, it seems) and after a long debate with an expert in the matter, who offered me a coffee in the end amazed at my supposed competence in planes' tech, the answer was it had Controllable Pitch props.
