1902 from Bruns & Deckel (Christian Bruns, 1853-1912 and Friedrich Deckel,
1871-1948).

Never. "D.R.P." is the abbreviation of "Deutsches Reichs-Patent" (German
Empire Patent) from 11. July 1877 to 1945. Since 12. August 1949 it must
be "D.B.P." as for "Deutsches Bundes-Patent" (Patent of the Federal
Republic of Germany).
