also just found the 386 factory engraved also not that i would sell but what would this be worth
Welcome to the group BrunoN!
There were many rifles in port when the George Bush the First declared features of a rifle cause their owner to become a baby killing machine. The rifle you have seems to be one of them. Original markings on many were scrubbed completely off, some obvious and some very well done. This included the importer that was supposed to get the rifle. It is very possible that yours was partly scrubbed, obvious by the 386 and serial number. The original importers names were scrubbed, the rifle then converted from the evil baby killing 56S or AKS-762 to the MAK-90 approved name. After the evil parts were removed to meet the new AT and unconstitutional F sporting purpose clause of the new second amendment, they were then sold to most likely the first importer to show up.
I don't believe Keng ever import stamped any MAK-90s and they don't have record of your rifle because it went to another importer who then put their markings on it.
Indykid, you are an absolute encyclopedia on the Chinese AKs! I hope you don't mind, but I'm asking you for advice before I ever pull the trigger on buying a Chinese preban AK
