Vintage B&O Railroad Advertising Pocket Knife

You are bidding on a vintage senator style advertising pocket knife manufactured by Quick Edge and stamped with the B&O Railroad logo. This knife is a part of a collection of 12 knives advertising 6 major railways ranging from the northeast to the southwest (see additional postings). This collection was completed by 1950 and, though the age of this knife is unknown, it is suspected of being pre-1940.
This knife has celluloid scales both of which are in excellent condition and fully intact. The blades have minimal staining from acid leaching as the celluloid aged and have never been sharpened. The springs and works are smooth and snap nicely.
This is an excellent example of a time now passed and would be a wonderful addition to any collection of advertising knives or railroadiana.
