Vintage WWI German Dog Tag in excellent condition with original leather pouch, also very nice condition. Dog tag reads Stamm Kompanie Grenadier Ersatz Bataillon #318. Blood type B, ID 33121. A Stammkompanie was a kompanie that trained the soldiers. Often the soldier of this kompanie were soldiers who had frontline experience and/or were no longer fully usable at the front due to injuries. Of course this changed later in the war as there was a shortage of soldiers). As a bonus... I have added a cool old German Compass and Opisometer (map measuring device, probably date closer to WWII). Compass includes a leather cover which is starting to dry from aging. Stamped made in Germany, which they did a lot after WWII. Thanks for looking.
