Not good. This dagger has been for sale for quite a while. This is a new set of photos of it. Notice how they are cropped just above the trademark. In fact, the trademark is too far from the crossguard for the blade to be authentic. The other parts may be good,
Gunbroker eh: I quit looking there some time ago. If there's ever a legit piece for sale it was either posted by accident or they're asking near retail as a starting bid. IMO: If you are unwilling or unable to dig items out of the woodwork; Buy from fellow collectors and dealers you know. Jim
