At this point I agree with Miller. I went through every thing I had. I even looked at Prussian, Hungarian, Austrian, Czech etc and there was nothing that resembled that 1st crown. There seems to be lettering in the crown. I am guessing that if you figure that the rest falls into place.

On Belgian and Spanish guns, a makers trademark is often stamped. Some times these are simple, a couple of initials, some times they are very complex and ornate. These marks change over time.
