Questions about Erfurt Rig

[phatrick88]

Have a matching bring back unit marked 1916 Erfurt that I have some questions about:

-The wood bottomed mag matches the gun but only has the last two serial numbers stamped, is this correct for an Erfurt of this year?

-The holster is unmarked and the strap has been replaced with a USGI style pull snap. I'd be interested to know more about the holster (issue, time period, etc)

Pics attached below. Would be happy to post additional photos or this luger's history as provided by the unit marking at your request. Thank you.
