Below is a page from a NIMROD GEWEHRFABRIK, THIEME & SCHLEGELMILCH catalog which I found on the Internet.
This is the only Nimrod catalog that I am aware of. There is mention of a 1914 Nimrod catalog in Russian sites and this may well be the same one.
Apart from a RWS factory drawing, this is the first catalog I have seen the 9.3x75 Nimrod cartridge shown in.
Does anyone else know of this catalog and if so are there other pages showing ammunition ?
