Found this page which mentions the Reserve Infantry Regiment 248 in the XXVII Reserve Corp having been formed in 1914. Mentions Reserve Infantry Regiments and Reserve Jager Battalions. So on this iston, is the "RJR" a Jager or Infantry regiment?

At the bottom of the Page there is a list of marking achronyms and meanings....
R.J.B. = Reserver Jager Battalion
R.I.R. and R.J.R = Reserve Infantry Regiment.
So now I know!
Thanks!
