This vintage hand operated Barber Hair Clippers are marked BOKER No. 000 Made in U.S.A. The markings are worn and hard to read with some of the markings after BOKER worn off. I found “History. 1837 - H. Boker & Co. was founded in New York City, by. Hermann Boeker, as a cutlery import firm.” They were cleaned, oiled and sterilized with bleach so are ready to use. They are well used with tarnish and wear in good condition.
