PeteM should have an opinion on any Italian similarities:

This one dates to 1930, a Model 1010 Pigeon.

The Italians did use the term choke & note the reinforcement / adornment on the tubes near the frame. Although another gunmaking center could have easily have adopted such.



Not the exact Sauer trademark as seen @ then of the Krupp Steel type, but Sauer did file for protection in Belgium in 1896 & had tubes rolled there. So the Italians / makers of the subject piece could have easily sourced Sauer sanctioned tubes from Liege.
