3/5/20 - This is a very nice example of a super rare Luger holster - the M1914 Navy. An example can be seen on page 140 of Still's Central Powers Pistols, but the holster is all correct and original with 1918 manufacture date. It is marked 'LZA' over 'J. Karlsruhe' on the back, front and inside the flap. The holster is in great shape aside from a small hall in the top of the front flap, and a previous owner has lightly scratched in their name and social into the back of the holster.
