Sometimes the handle and cross-piece have markings and perhaps your's does too?

Some of the F/S knife scabbards that I have seen have been in significantly worse condition than the example shown in post 1. It all depends on how much use the knife in question has actually had, I guess. The bluing to the chape to the scabbard, post 1, looks to be in almost perfect condition, so perhaps it's been re-blued, or perhaps the scabbard is not original to the knife?
