Here's two that back in the day are somewhat different but still a pair. Two totally different blades and grind lines; even the hilts are different. I believe the bottom knife is a wide blade (correct me if I am wrong). Late 40's 4-7, brass hilt,7 spacer, pinned stag, black compass, riveted Heiser sheath. Early 50's 4-7, brass hilt, 7 spacer, red pinned finger grip stag.
