In the last week I have seen two K98Ks with stocks that have a flat buttplate and no takedown disc. One was an RC and the other was advertised as an all matching Mauser Berlin-Borsigwalde 1937. Don't want to post pics as they are active auctions. No interest in buying either of these, but am interested in the provenance of these stocks. They look very similar to a yugo stock (could be what they are with a K98 handguard?). I have seen the stocks without take down discs in the Kriegsmodells, but not with the flat buttplate and not in the 1937 243's. Thank you in advance for your thoughts and ideas!!
