Imho this rifle was not made by DWM. It is merely chambered for the DWM made M93 7mm = 7x57 cartridge. As to cartridge dimensions not very much was standardised before WW1, so it was wise to mark exactly what cartridge make the rifle will certainly take, especially on rifles made for export.I have seen the same bolt handle shape on several post-1908 Haenel sporters on M88 and Haenel M1908 actions. Remember, these Haenel sporters were not built on surplus ex-military actions, but on new-made by Haenel M88 type ones, just as the M30 Remingtons were not surplus M17s.
