The lettering looks Yugo, compared to Yugo things I have. I'm not sure what it is when people either post dimensions with no photos or post photos with no dimensions. If you look at the top left of the case lettering you can see the mm from the size, but that info isn't included in the photos. Usually these cases have the mm size and even gun they are used in, if you only photograph all the lettering.
Can you write to the guy that has the case, and ask for dimensions and more photos?
Way ahead of you, I asked for better pictures of the marks on the side... he did list it as 76mm though. As soon as I get more info, I will post.
