When searching...... for the "Nimrod - Nasenverschluss" made bythe Suhl rifle factory Thieme&Schlegelmilch, one comes across weapons that explicitly refer to a patent for the breech. Not all weapons with this locking system bear this marking.

A search in the magazine "Waffenschmied" from the period 1895-1910 reveals only one DRGM (this is not an patent!) with the number 136215, which describes a rifle breech.

A search in the DEPATIS patent database with various keywords yields no hits.

There is also no reference to a patent or a patent number in my relevant literature.

Was a patent granted for the "nose lock" or is the information on the weapons misleading?

Here is an example, taken from
