Hello, I hate to bother people but I have been looking for hours trying to find these Small pins. From Maybe what I gather could be From 1942 paratrooper lapel pins. But I am sure I am wrong .Lol They are very small about 1/2" . Appear very old and the silver one looks like 3 parachutes dropping to earth? Only markings are on the front. Most of the Japan early leaves do not have a pointed leaf as this so I really do not know , Thanks ahead for any help ,Much appreciate.

I think these are the insignia of students in the WW2 age group.

"高" means high school student, and "中" means junior high school student.

Please note that this division is an old system that is slightly different from the current school system.
