I remember Chinese AK's in Woolworth's sporting goods department of all places, in the late 80's.
Looked through my 1981 Gun Digest, it's AK free. No Valmet, no Norinco. Doesn't mean they weren't in there before and after,
Armalite, Auto Ordnance, Colt, Commando Arms, FN-FAL, Iver Johnson, Ruger, Sig-AMT, Springfield, Wilkinson and Uzi were all there.
