1917 DWM Artillery unit marks.
 

I have the chance of purchasing quite a nice 1917 DWM Artillery which is complete with board stock, holster,tool, mag pouch,cleaning rod.
The back grip strap is unit marked JR 448 9K and the holster is made by Max Reuser Stalluonen 1916 and is stamped BAX VII.
Can any one help with the unit marks for the gun which I interpret as Infantry Regiment No 448 , 9th company staff. I have never seen a unit mark on the back grip strap before, has anyone seen similar and the holster BAX VII, I have no idea.
This gun is a WW1 souvenir and has papers but nothing on the unit marks.
Help please,
Murray,
