M-section Italian system with hose connector and O-ring »galvanized«
This system has a lever permanently welded to the M-section. There is a ball with a loose clamping ring on the V-section. The ring must have a sharp edge where the lever of the M-piece engages. If the edge has been processed so it is round, it is the »Bazzoli Siegperle« system. 
 
To determine the size of the Italian coupling, measure either the outer diameter of the V-section or the inner diameter of the M-section. The outer diameter of the V-section or the inner diameter of the M-section must be the same for the M-section and the V-section. The coupling hose connector is measured on the outer or on the inner hose diameter.
