Where bouts in Arkansas you from? A lot of Arkies served in the Pacific in WWII. Know if your Dad was there? A large Japanese-American relocation camp was located about 20 miles from my home,I doubt that Jap bayonets were popular items there,but a returning GI assigned as a guard might have brought one.Not to mention these and other WWII bayonets were sold by the thousands in the proliferation of Army surplus stores that sprang up following WWII.Could have been given to your Dad by someone too. No telling how many of these things are hiding in attics and garages,on old barn shelves and the like,waiting to be discovered.Sadly,many get tossed into the trash and end up in some landfill.Too bad there,s not a society for the rescue of old militaria.Hope you find the story on yours,if you do be sure to let us know.Fellow Arkie.
