Help in identifying Italian silversmith "8 CO"

[Iuliia]

Please could anyone help me to identify the Italian silversmith on this piece of silver. I've managed to confirm that it is Italian, .800 purity silver, made between 1944 and 1968. The 'lozenge' mark includes "8 CO", which I suppose stands for "Como".
