6/8/21 - This is an original WW1 Imperial Navy Luger Magazine. These are scarce magazines and hard to find all original like this example. The base is crown over "M" proof stamped and numbered 2771. The base has no cracks or chips. The spring is strong and fully functional without issue. The tube is numbered "1699" on the spine, which is likely a unit number. The tube has some small areas of discoloration but no major issues.
