Bruce picked this up at my request at a show he was at. I have an LK5 marked 98k and wanted a companion Beutewaffen with the same marking. From online searching and speaking with other collectors, the LK5 marking is as of yet unattributed. There are a few theories, but they are just that, theories. I suspect that the marking is German, and associated with a rework facility, perhaps in the French zone of occupation. The majority of arms with the LK5 marking are French, with some German, Greek, Yugoslavian, and other non-standard weapons. All seem to be wartime or pre-war rifles that have the marking, and a few vet bringback type rifles have LK5 markings (other LK markings exist, such as LK4, LK3, LK2, etc.)
I'm not a French rifle collector so I'm not certain what is numbered on these, but the front band is numbered with 2 digits which I believe are unnumbered on French production. Bolt is Electro penciled to match, and my dou43 K98 with LK5 marking has EP'd parts (along with other reported LK5 marked guns). Not all LK5 marked guns appear to be reworked though, which in itself doesn't mean a lot as there are WW2 German 98k's worked on by depots that don't necessarily show rework traits.
