Congrats on your new rifle! You have a rare specimen there. I recently became a new owner of a Clayco as well by luck since I wasn't out looking for one and have no prior knowledge of Clayco AK47. It was my friend who told me to jump on this Clayco he saw online. The action and trigger feel on these are amazing and by far the best factory AK I'd tried. I couldn't bring myself to shoot it. Here is what I came across from a little search.
Article from 1984 Soldier of Fortune magazine on the Clayco
The AKS (it was an AKM-type, and called the AKS by Clayco)-
It was available with a standard fixed stock (black fiber-reinforced phenolic), or as an underfolder. I thought it was kind of interesting that the fixed stock, and folding stock, models were made at different arsenals and finished slightly different. The fixed stock guns were made at Ling Hua Arsenal and had polished bolts and bolt carriers. The folders were made at Min Shan Arsenal and had gray phosphated bolts and carriers.
They came with one magazine- blocked to five-round capacity.
The AKSs did not come with bayonets either.
However, you could get an "accessory kit" that had two 30-rd magazines, and a bayonet with scabbard. The bayonet did not have the wire-cutting feature.
Price on the AKS? The standard stock: $499.95. The folder got a premium: $574.95.
