I was kind of thinking AK too, but it seems a bit different than what I have seen before.
How many types of guns used this style of kit?
I was also under the impression that Yugo 59/66s were supposed to have the earless kits too, with the brass tools...but rarely do I see earless ones offered as SKS kits, they usually state they are AK kits.
Proper cleaning kits are a little facet that I like to cover when restoring....
