Got me wondering, were these maybe from the same place as the G10, Bosnian import M59/66 in almost M59 configuration. As I understand, they had new barrels, and didn't use standardized Yugo serial numbers. So, were they new receivers, they didn't look scrubbed, and the serials are blued as well, if my febble memory serves.
I mean a new etched number on a "reblued" refurb, not stamped. But yet, barrel and receiver match, and the hidden barrel and reciever numbers are, blued.....Hinky!!! And if it were a refurb, it would have been serial stamped way back when, so why reetch, the same number??
The plot thickens....
Interesting, I hadn't heard of those:

If these are newer (1991-2005, after Slovenian independence, pre-storage date) Slovenian assemblies then they must have been from old parts, perhaps without any SNs since they have the part number on the bottom of the receiver and the odd etched SN, perhaps old
used parts judging from the bore.
I'm still not seeing any story line that is convincing. Definitely an odd combination of features in any case. It seems at least rational and plausible that Slovenia, with limited access to arms after establishing independence from Yugoslavia/Serbia, may have put together all available weapons it could from whatever parts were on hand, so maybe these are later assemblies. They certainly weren't getting any more of these Yugoslavian SKSs or any other weapons from Serbia after 1991, and the other break away republics needed everything they could get their hands on, so I doubt Slovenia which escaped Yugoslavia with relatively light fighting received any SKSs from Bosnia or Croatia. Did Slovenia have a refurb facility when Yugoslavia was intact? What was it's designation? We can eliminate TRB and TRZ in Bosnia and Serbia, respectively. My stock at least went through TRZ at one point.
Like I said, none of the story lines convince me, not even any I can come up with. We need more data!
