It might take a little effort when typing, but letters and numbers are cheap online- so
why not "alphabet commercial(formerly identified in error as 1923 commercial";
or "new model parabellum(often referred to as 1906 model).
"Black Widow(a fantasy/marketing name for an all blued Mauser P.08 with black grips)"?
Each time we use the correct terms, we make a little progress. JMHO.
When searching online, I just use "luger"; one never knows how anyone will describe something special; occasionally I toss in "Lugar(sic)".
