OWD,not me. The Austrian (germanic as they come) gun I have has
Kersten locks that include underlugs as compared to
Cman's that only has the crossbolt (like the Beretta SO's).
First time I see that hinge system too.

P.S.: Cman, "Fabbrizioli Mario" appears here towards the bottom
of the list of Italian gunmakers but no additional information:
