the first # is Kg 1,500 and that is the barrel weight - 1.5kg
left bbl - 18.3mm/ o.721" / o.677" choke for 0.044" choke
right bbl - 18.4mm / 0.724" / 0.701" choke for 0.023" choke
nothing unusual about those #'s
** a pic of the bbl flats would have more data **
there is usually a model # somewhere, could be under the trigger guard, maybe on the action flats
the 20,3 and the 70 could be some kind of date code but it is not the standard format for that OR chamber length (cam.70) or anything else that I'm familiar with
not being mean but the #'s look a lot sloppier/older than the ones on a 1969 gun I have so ..... FWIW
I'm no Beretta expert but Italian guns all meet the same criteria for markings, proof, etc.
