The Welsh Fusiliers Knife
This a very rare one to find, even the reproduction model. Originally purchased by Lord Howard De Walden for his machine gun sections they were fearsome trench weapons. Hard to believe they were WW I weapons, they look like they could be fighting against William Wallace.
These are fairly easy to tell apart. The blade is much thinner as is the guard. Easy to say once you have seen both, tough if it is well aged. This specimen still has the packing grease on it from overseas shipping. The scabbard is cloth over leather like the originals and very badly hand stitched. Extremely expensive should you find one, beware.
