Designed for Veterinary use on large animals, these antique syringes are quite large, and unsettling. This piece was made sometime during the late 1920’s or early to mid-1930’s. The O.M. Franklin Blackleg Serum Co. Syringe still has the original red colored stopper, as well as an original needle in place. This piece is in great shape, and damage free other than age related patina, and could probably be cleaned up a bit if you chose to do so.
