How were GEM rifles originally shipped? Were they boxed in some way?

I ask as I have acquired a Gaggenau (the crossed pistols) heavy GEM in a box. Box fits the rifle perfectly, three brass hinges two swing hooks on the front and a broken central catch. Stencilled on the top and bottom is the word GEM in light blue paint. The serial number is added in by hand on the bottom. Box is professionally made, though needs tom TLC today.

Is this an original Gaggenau GEM box? Anyone know?
