Provenance: The makers have kindly confirmed that the guns were completed in 1984, and that "they passed the not the standard (mandatory) proof, but the High Pressure Test at the Proof House in Italy".
The wall thicknesses of this pair of guns read below the standard recommended minimum for vintage guns, however, the makers have confirmed that with certain grades of modern high resistance steel, different guidelines are laid down.
The method Fabbri use to produce their steel, vacuum arc remelting involves being twice melted down under vacuum conditions to ensure that it has no impurities, inclusions and shows isotropic mechanical properties.
Fabbri kindly inform us that " The European C.I.P. (Commission Internationale Permanente) for our kind of steel permits minimum thickness of 0.30 mm (12/1000"), and for the 2 less resistant class of materials 0.40 mm (16/1000")."
