Pad, I couldn't get a specific production date for this particular pistol. My Blue Book of Airguns, Sixth Edition. refers you, for Norica guns, to American Arms, Inc., where it says they imported Norica from late 1988 until 1989. It mentions the Commando model, but gives no specific dates for it.
The book also refers you to S.A.E., who imported Noricas: but then proceeds to not list S.A.E.
GRRRRR!
