I have a shot at picking up a Schrade WWII era H-15 combat knife. I am passingly familiar with the Ka-Bar, Ek, Cattaraugus, Sykes-Fairbairn, etc. knives but this is a first for me and (I assume) not too common. It's not as nice as the one pictured and has no sheath but it's free of any coarse damage or signs of abuse. Your input would be appreciated.
