This is a great 2nd pattern British WWII Fairbairn-Sykes Commando fighting knife.  The tang is marked with the British military Broad Arrow stamp and "B2" to one side and "England" on the other.  Blade is very clean, nice blued tone.  This knife comes with an original sheath.  It is missing one of the straps and elastic band.  Leather belt hanger is worn at the top of one of the slits.
