I recently found this great ad for sale in the internet.
It is listed as a 1897 ad which is unusual as the dates in the ad seem to be all 1898 which is the accepted date for this cartridge.
There are supposed to be two be two patents (D.R.G.M.) related to this cartridge:
- one is for the Lead alloy bullet which Brenneke is supposed to have invented in 1897. I have read somewhere (??) that the patent for this was applied for in 1899 and granted in 1900.
- the other is for the case which I believe was “D.R.G.M. 96541” and cartridges with that hs do exist. This was evidently not uncommon and occurred for the 9.3x82R Nimrod (ie Thieme and Schlegelmilch) and 9.3x62 Mauser (G.C.Dornheim for Otto Bock). This gave the inventors evidently 3 (D.R.G.M.) or 6 (D.R.P) years of protected production for that case.
The ad shows two D.R.P. patents on the left; D.R.P 94620 and D.R.P 95046 - both evidently for the Brenneke Drilling mechanisms which were invented by Brenneke in 1895 and both were granted patents on 27 Nov 1896. These patents are unrelated to the case and bullet.
I was hoping that the ad may provide more info but the problem I have is due to the very ornate nature of the font used. I find it is extremely difficult to work out some of the letters so that the words can be translated because I am not sure of what I am looking for. If one of our German speaking members could help me there with a translation I would be very grateful.
The other question is - I used to be able to find some early patent info online for the German D.R.P and D.R.G.M. patents but no longer can find the reference. Does any one know of a link to such info on the Internet ?
