My older brother, a US Navy sailor, served aboard the USS Teak, a sub net laying ship, later converted to salvage operation, he was a "plank owner" and aboard for the entire Pacific War. Immediately after Manila fell, his ship was assigned to salvage duties in Manila Bay, where he remained until after the Japanese surrender in 1945. He brought me back these knives and bayonets as souveniers when I was only 6 or 7 years old, I have owned them ever since. I am now to the point in my life when it is time for someone else to share the joy, so will be putting them on the block and need expert counseling as to whatever value they may have.
First picture is of some Filipino swords and a knife. I'm pretty sure the larger ones are more ceremonial than practical, but they are made of good steel and VERY SHARP. The wooden scabbards are made of a light wood, not balsa but I suspect maybe bamboo. The tip of one is broke off from when I took them to school for show-and-tell when I was maybe in the 4th grade or so. The little knife is very crude as is the scabbard, I remember my brother telling me every Filipino kid he ever saw had one of these on his belt.

Second picture is of some military bayonets and a knife. The knife is US Navy issue, he told me every sailor carried one of these for shipboard duties, I don't know if this was his but it came off that ship. It has the scabbard and is marked "USN MK2, B.M. Co." and "NORD 4733". The metal on the hilt is patina, otherwise this outfit is in good condition. The US bayonet is marked "SA (bomb emblem) 1918" and there is a serial number, US 975xxx. This outfit is also in good condition. The other two are English, (makes me wonder how they got to Manila) They are both marked Wilkins 1907 with some proof marks. The one leather scabbard has started to separate at the tip, the other is intact. Both show signs of hard use.

I hope there are some folks here that can help me with the possible values, I searched fleabay , no joy, googled around a little , still no joy.
Thanks.
