Question concerning VVS' Boston A-20 subtypes

IIRC A-20G-1 4*20mm + 2*.50 in nose and 1*.50 in dorsal position + 1*.30 in ventral tunnel
A-20Gs from G-5 to G-15 6*.50 in nose and 1*.50 in dorsal position + 1*.30 in ventral tunnel
A-20Gs from G-20 onwards 6*.50 in nose and 2*.50 in dorsal turret + 1*.50 in ventral tunnel
A-20J & K 2*.50 in nose and 2*.50 in dorsal turret + 1*.50 in ventral tunnel

And IMHO that was also what Kurlannaiskos wrote.
