Trucks identification

[Attilio]

Thanks for the responses!
I haven't any data where the cations where taken.

The truck in the pic n. 3 is a captured CMp manned by Italian Bersaglieri with a Breda 20 mm truck mounted gun.
Can be a C 60 L?

The pics n. 4 is a Conus gun, a free french truck mounted 75 mm mod 1897 gun but I dont know if it is Ford or Chev
From the census number 4713127 it is possible to establish if is a Chevy truck?

Thanks

Attilio
