Xtra Clean Wwii Era Mystery MK1 Fighting and similar items

UP FOR SALE IS WHAT SEEMS TO BE A VERY CLEAN WWII ERA MK1 FIGHTING KNIFE. WHY "MYSTERY?" BECAUSE IT IS ONLY MARKED ON THE RICASSO AS "MILITARY," ACTUAL MAKER IS UNKNOWN. BUT!!!!!! FOR WHAT IT'S WORTH, AN INDEPENDENT COLLECTOR ACQUAINTANCE SENT ME AN IMAGE THAT LOOKS IDENTICAL TO THIS ONE, BUT HIS IS MARKED "KINFOLKS" (THIS ONE IS NOT MARKED THAT WAY.") SEE THE KNOWN KINFOLKS IMAGE ATTACHED. IS IT POSSIBLE THIS IS A "PROTOTYPE?" ALSO SEE THIS "MILITARY KNIFE ISSUE" DEALT WITH ON PAGE 101 OF "COLE'S 'THE BEST MILITARY KNIVES..." IMAGE IS ATTACHED. IT'S A WELL-MADE QUALITY KNIFE COMES WITH WHAT APPEARS TO BE ORIGINAL LEATHER SHEATH. THE BLADE IS "BRIGHT POLISHED" VERY SHARP! FEATURING A BLACK PLASTIC BUTT. FROM A SMALL CENTRAL FLORIDA COLLECTION, AS FOUND AS IS :) OVERALL CONDITION IS EXCELLENT ... SEE IMAGES. BLADE SHOWS HANDLING MARKS BUT NO CHIPS, BREAKS OR OTHER SERIOUS DAMAGES.
