The "Real" type 1 AK is non-existent. It was a pressed steel receiver gun that was only made for a very short time. The second issue, which most folks confuse as the "Oldest" AK, has a milled receiver and screwed in, rather than pressed and pinned barrel.
Complete, factory semi-auto Russian AKs have never made it to these shores. Only Russian parts that were assembled into rifles here. The only Russian Post WW2 semi-auto rifle to ever be offered here is the SKS design. Companies like Century International, K-Var and others make AK clones. There are also milled receiver guns available out there.
