Polish Model 1954 Air Force No Maker. Blade #15124. Dagger is 13 1/2", 14 5/8" with scabbard. The dagger has a 9" nickel plated diamond cut blade. This is the silver plated model. All fittings are silver plated . From my observation, the 1970's change from silver plate to nickel plate took place at about #15,000. The scabbard is covered with black leather. Note the large eagle without crown on the pommel and the Polish Air Force symbol on the upper scabbard fitting.
