Help with R78 R974

[Rudolf44]

Hello,

Sorry if I post in the wrong place...
I’m looking for accurate infos about the Roll T78 R974. On the NARA-Guide 96 we can read for this Roll : H6/541 Regimentskommandeurliste, undated, 42 pages.
But which Regiments it is ? Inf./Gren.Rgt. ? Art.Rgt. ? Pz.Gren.Rgt. ? or something else ?

Any help is welcome

Rudolf
