Holster Identification and/or Info

[gunbugs]

The "M"over anchor on the holster denotes Navy issue (Marinen). I think the repair at the toe is post war. The Aluminum bottom magazine mark "N4401" is a "Nordsee"(North Sea) Navy property mark/serial number. I think the holster date may be 1937, which might jive with the WAa stamp, which has partially obliterated the date. Someone else will have to chime in on the other markings,(police?)
