Hilt is ~6-1/2" in length - including basket crossguard.
Interconnected (riveted in some locations) sheet-steel grid basket with forged-steel "D"-guard. "Bird's-head" pommel-cap, also steel; Grip is wood, was wrapped in cord, over-wrapped in a layer of leather, presumed to have had a twisted-wire wrap on top of that.
