Just post a WTB note in that section. These have come up for sale recently in the sales section. The .45 version comes up for sale with some regularity. Finding the Euro case for it is something different.
The Euro cases do appear on here (and many other vendors) pretty often this past year. John (Flagman) has sold a few for the past few months. I would get in touch with him and see if he could put you on a waiting list.
The aliminum case in the picture is not a Euro case. It is the "so called" mid-Eastern contract case for the Mark 23 SOCOM. The black Eagle case it came with is what I want with the pistol as shown in the picture. It has the red HK emblem on it. And, not the Blackhawk case, either. Thanks.
