Here are some marks on a couple of Remos(Script) and in particular I'm looking for the K beside the steel type stamp, an EHK(script or not) and a Sl tube makers mark(possibly Belgian sourced):


Gewehrfabrik Remo was a maker to the trade and I believe this drilling to have been peddled by Gustav Wahrenberg of Brandenburg


R over W stamp also

Kind Regards,
