The one presently available from KA-BAR is NOT an original military issue pommel. The available pommels are thick pommels with a pin hole halfway through them. NONE of the original MK2 knives by KA-BAR with the thick pommels had any pins in them at all, they were peened on. No KA-BAR MK2s have been purchased by the US military since WW2. The other problem would be that if his knife is a later model one which did have a pinned on pommel, but those pommels were thinner than the ones currently available. There are plenty of really bad condition MK2s out there to take a pommel from, or one could have a machinist turn one out. Naturally it would be good to see a photo of the knife.
