Yes, I have one. Mine does not have any visible primer seal. This is the first I have heard of one that does. I am surprised it is not black, but then if made for some other country, the color could have been specificied. I say “black” becuase the 1975 and 1977 runs of the Thun 9 x 18 mm Police loads normally have a black PA, although I have one 1975 round that does not have any visible seal.
The time-frame interests me as I did not have that information. That fits in with the production of the 9 x 18 mm Police, not that it needed to, necessarily.
Is that a good, firm memory on when you acquired it?
When I made all my inquiries to various Swiss sources concerning the Makarov rounds, most were met with denials that Switzerland ever made that caliber for any reason, and fell back on the idea that I was confusing it with the 9 mm Police. That proved, of course, to be completely false. I don’t know if that was subterfuge, or just ignorance. Similar inquiries about the Thun-made 9 x 23 mm Winchester cases made for Swiss IPSC shooters was met with total ignorance, even by some employees involved in ammunition production. Finally, thanks to advice from Frank N. (local .223 collector), I found a lady RUAG who knew everything there was to know about the 9 x 23 production, and gladly shared the information with me. There was nothing secret about it, so in that case, the lack of knowledge about it was simply that, ignorance.
I will check with the Lab and see if their specimen has a green primer seal or not.
By the way, there is no question that my round IS the Swiss one.
