WW1 Imperial German Prussian Belt Buckle & Leather Tab 1912

A pre-WW1 manufactured M1895 Prussian buckle with its original leather tab, the tab is maker marked 'H.Clemen, Elberfeld 1912' and is in very good condition with all its stitching intact. The buckle has not been messed with or cleaned as there is some period staining present, this does look like a splattering of blood, buckle possibly removed from a fallen soldier.
