Hey guys. I’m having trouble identifying a 1916 luger I bought a couple of weeks ago. It was converted into a carbine by one of its previous owners, and I’m thinking about re-barreling it and removing the foregrip mounting bar, but I’m unsure if it started out its life as an army luger or a artillery luger. I suspect it used to be an artillery luger because it has no rear notch sights on the toggle, and if it did they were expertly removed because it looks like it never had any. Here’s a photo for reference:
