Question Help Identifying a 1st stage

[butchkhan]

Friend of mine says its an old model atomic but I have doubts. It has no markings except for a stringnof numbers. It has 2 HP ports and 4 LP kn a swivel with a bottom port that looks like its also LP.

No idea but doubt it’s atomic, looks like a MK 20/25 clone to me.

Check vintage regulators on the following; CRESSI, INSPIRE or ScubaPro MK25

also check EZDIVE regulators made in Italy

It's an Akuana first stage. Checked their website and they are based in Italy. But thanks for all your inputs.
