Ganna 1939
Gloria 1941
Maino 1936
Bianchi 1941, 1949, 1950, 1953
Again, not suggesting that this frame is from any of these makers as I am outside of my expertise on this one to be sure. Juvela would know if the Bianchi seat lug was proprietary to them . . . the other marques listed may have used the Agrati product(s).

Pre war binder bolts in front of the tube are common like dirt. I can't think of a major manufacturer who didn't do that. Most being on top, with Legnano being somewhat of an exception with the bolt below the top tube. Except the lone year of 1925 when Legnano had it on the top.
But post war it is not common. Granted, it is possible this bike could be prewar. Simplex was available then. It's just not very likely. I am 99% confident it is none you listed, the build characteristics of the OP's bike do not match what's typical for Gloria, Ganna, Maino & Bianchi. If I were to make wild-ass guess, I'd say it came out of a small shop in the greater Torino area. Which, I haven't a clue.
