I wasn’t trying to be rude, as a French, I was just very surprised by the term you used lol. Have you tried googling levrette in French ?
That’s why I highly doubt that it’s its name but I’m not an expert either.
Not even that. Oerlikon is the name of the company, and the company’s name derives from the name of the Suburb of Zurich where the company is located.
Oerlikon (or better Oerlikon-Bührle) is well known for canons which in WW2 were used both by Axis as well as Allied forces, unguided rockets (iirc most of the rockets we see on Swedish J29, J32 etc are from Oerlikon), and also later produced many well known if not iconic canons (like the ones arming Gepard, SIDAM, Viggen,…).
Eh German. Swiss, Austrian potato potato. All 3 speak a beautiful variant of German. That and it’s 5 in the morning so my brain is running on fumes of dopamine :D and can’t tell the difference between of current. My bad never the less.
