Okay I need a little info on my latest combat knife..."USMC type, kabar pattern' , Same size and blood grooves, USN stamped, MK2...stacked leather handle. Scabbard marked Nord_6581, BMCO /8 V* P*--- any way it is rough and missing about 1 1/4 inch of the leather from the handle...I know you can punch out the pin and remove the pummel and add leather back to the stack? Where is a source for the cut leather pieces, and who has a idea where to look up data on these knifes..I have several reproductions, but this is the first old one..OG.
