Methinks that you're 1868 victorian underwear. Is rather quite revealing. But, before I get pfft again. I mean that in a good kinda way. Because it shows that your character has some sorta swagger about it.
Okay, you don't seem to know much about guns and I don't think I know much more! However as far as I can discover Mauser never made the Pistol Parabellum AKA Luger P08. Here is the Wikipedia page: https://en.wikipedia.org/wiki/Luger_pistol.
I should add your depiction of a Pistol Parabellum AKA Luger P08, is quite good. So very many artists don't do much better then two co-joined boxes, so good on you for doing some research.
It just occurred to me that in the world where Ariane exists, well who knows, almost anything is possible.
some technical details
Militärische Bezeichnung: Pistole 04, Pistole 08, Ari-08
Entwickler/Hersteller: Georg J. Luger
Entwicklungsjahr: 1893 bis 1908
Herstellerland: Deutschland
Herstellerfimen: Mauser-Werke

PS:
The austrian Georg Luger based his design on the older and bulkier Borchardt Pistole. It was produced by several factories in germany and switzerland and some other countries. In germany all Lugers (even those made by other manufactors) are usually refered to as Mauser, as most still existing Lugers have been made by Mauser, they even produced some as late as the 1970s.
