Luftwaffe combat boot knife or Stiefelmesser marked W

A very nice original Luftwaffe combat boot knife or Nahkampfmesser. This is a very rare example which is not marked with a typical Luftwaffe Waffenamt but with a “W” on the blade! The knife is in good sharp condition and has never been issued, cleaned or sharpened post war. Perfect rare example which would be a great addition to any combat mannequin or a focussed knives/bayonets collection!
