The stuff Grandpa brought back from WWII. He was a Tank Scout for the 2nd Marine Tank Battalion and fought at Tarawa, Saipan, Tinian, Okinawa. Spent the last few weeks overseas on Occupation duty near Nagasaki. Thats where the Beauty Kit and Kimono came from.
The three knives in the case are all War items too. The one on the right is the "Marbles" brand knife Grandpa carried throughout the War. He said the Kabar that he was issued was a "piece of crap", and he tossed it into the Pacific. His Dad mailed him the Marbles Knife and the Colt Revolver while he was still in Tank Training at "Jacques Farm" in California.
The two knives on the left were both brought home from Germany by his brother, who was with the 42nd "Rainbow Division". They don't look to be Military issued knives, at least not any German Military knives that I've ever seen.
The Arisaka is one of the relatively few that made it home with the Chrysanthanum Seal intact. Thats because Grandpa's M1 Carbine was destroyed in a mortar attack. He found the Arisaka later in the day and carried it until he got a replacement for his M1.
The Sword was in perfect condition until he mailed it home. My Great-Grandpa used it to chop weeds. He said it did a great job cutting horseweed...
The Flag came from either Saipan, or Tinian. He doesn't remember where he picked it up. The Marine Cap isn't WWII era. I bought it for him a few years ago.
