Regimental Marking

[lonewolf523]

Gents,

I have add a picture of what I think is the 99th Infantry Regiment 6th Squadon, 10th Weapon. It is on the back strap of an Artillery Luger. I also am having problems finding the 99th Regiment during WW1. Any help would be appreciated.

Thanks as always!

Ordinarily, the R read after the numerals would indicate a Bavarian Regiment. However, there was no 99th Bavarian Regiment (Infantry or Artillery).
This would then suggest the Prussian Regiment 6 (though the 6 is somewhat wonky and one would expect the regimental marking to be a one-piece stamp.
If this is the case, I cannot say what the remaining numerals would represent (perhaps, weapon 99).
These are just my initial thoughts and I look forward to more experienced interpretations.

Incidentally, the Prussian 99th Regiment was part of 30. Division, XV Corps.

Sorry for some reason the picture is upside down.

Yes,
It's the Infanterie Regiment Nr. 99, 6.Kompanie,Waffe Nr. 10
(6.R.99.10)=Prussia.
Look ;
IR 99 – GenWiki
Bavarian regiments have a "B" in front of the unit "B. R." (Bavarian Infantry Regiment No.)
