There are a lot of questions regarding the state's production capacities: what did Serbia actually possess in 1907? Manufacturing artillery shell casings requires specific machinery and tooling, as well as the necessary skills... We also have to consider where Serbia sourced the semi-finished materials for the casings—again, a specific alloy... So, until that supply chain was established, I assume it was a matter of imports—and then we’d have to discuss the source... Who established the shell-manufacturing facility in Serbia, and when? I don't know that off the top of my head... A machine shop for bullet bodies is one thing, but this is another highly specialized type of arms production facility.It looks as if that Rheinmetall look-alike logo is in a square-like figure. Possibly not a Rheinmetall logo. It also made me think about the Serbian 75 mm M1907 mountain hun shell cases that also have a Rheinmetall look-alike logo, but are highly unlikely really Rheinmetall.
Yes, that’s right—in open-style lettering, they always look "neat," but that’s precisely the problem here: this logo isn't an open-style wordmark, nor is it a famous logo like Krupp, Škoda,Bofors etc. or anything of that sort; for reasons unknown to me, it is an obscure logo.Wouldn't German stamps be a bit neater? They are always organized, even the export ones.
