I saw Buds had the majority of them, one dealer here in WI had them on gunbroker for a stupid price compared to Buds, but I ended up ordering two glossy blued ones from Buds.
I could be wrong, but I believe these were a special run back in '13 as a friend of mine bought a gloss blued CZ 97 also made in '13.
It is a nice blue for the money, I don't believe its polished as it looks a little watery compared to my Hi Power and Colts but IMO the 75B looks the best w/ a blued finish.
