These belonged to my uncle. He was stationed in Edmonton, Canada during WWII.
I am not familiar with military pins so do not know what to tell you about it. Of the 3 larger pins, one is silvery or chrome, one looks like brass and one looks like copper. If you would like a better picture of a certain piece or have any questions, please contact me. Thank you!
