UBB.threads Forums Edged Weapons Miscellaneous Dagger Forum 1st Railway by Holler???

There is a single throat screw on the reverse side. There is a 1st Railway by "WKC" in Johnson's book, which he emailed me is original. Someone has to be wrong, either the "Klass theory" is wrong or Johnson's book and other dealers selling them are wrong. Any thoughts on this, thanks, Mike
