I just received a message from Denix, with an image showing possible items to be made by them in the future. And there is ... a Sterling (and a few other interesting things ;)). It is a C1 Sterling though, so I wrote them a long message explaining the differences between Mk4 L2A3 and C1, both from military point of view, as well as Star Wars point of view, and I attached a few representative images for them to understand better. And in the end I told them they should make both the Mk and C1, because Star Wars fans as well as military and gun replica collectors and enthusiasts will buy both versions.
