I am aware that Kabar was a union cutlery, but this has I believe mfrs ( I can't tell if the second letter is F ) above union cutlery co. It also doesn't say where it was manufactured. I know that it's old and deserves to remain..any knowledge of this knife would be greatly appreciated. ~ JP
You have an extremely rare knife there. it was made by the Union Cutlery Company of Chicago, Illinois. They were in business for about 2 years from 1887 to 1888. They are not related to the Union Cutlery Co of KA-Bar fame and pre-date them by about 20 years or so.
