The design is generally called a jaeger, i.e. a hunting rifle designed for carrying while actively hunting game. The thumb trigger is curious, I have never seen one like it, although I have seen thumb triggers on other German rifles. And yes, "Teutonic" is the descriptive word for that one. Beautiful!
FWIW, 10.75X60Rmm is indeed a version of the 11mm Mauser. There were two loadings, one for the 1871 rifle (11.15X60Rmm), the other for the 71/84 rifle (which had deeper rifling, hence the smaller bore diameter), with slightly higher pressure and a paper patched bullet (very similar to our own 45-70 loadings in 405 and 500 gr versions). The 11X60Rmm was a very well respected cartridge in its day, and was even loaded in a rimless version after the advent of smokeless powder repeaters. Ballistics are close to 45-70 ballistics, being a 44 caliber 385 gr bullet over 60+/- gr of BP launching at about 1,400 fps (slightly slower in the older version). I shot my 11X60Rmm 1871 rifle for several years, loading it with paper-patched cast 350 gr .429" bullets (designed for 444 Marlin) over 60 gr of BP. Very satisfactory.
Never try to educate someone who resists knowledge at all costs.
But what do I know?
