The 1930's Anton Wingen Jr. "Deutscher Brummer" catalog picture shows the term "Ges. Geschutzt", pronounced "guess-shutst," the term is an abbreviation of gesetzlich geschutzt, a German phrase that translates as "legally protected" or "copyrighted." and was used since 1899.

The D.R.G.M. signifies "Deutsche Reich Gebraumeister" and is a design or use patent somewhat similar a "Registered" mark that provides an initial three years protection extendable for another three years to six maximum. These were first issued starting in 1891 and were discontinued after WWII (1945).

I have never seen an actual example of the Anton Wingen Jr. "Deutscher Brummer" with "(Ges. Geschutzt)" and it is possible it was only used on the 1930's catalog picture and the actual knives had "(D. R. G. M)" and were not different from the original production of these knives, except for maybe the scabbards.
