Designed for Veterinary use on large animals, these antique syringes are quite large, and unsettling. The largest measures an impressive 9” in length when the plunger is fully extended: it was made by O.M. Franklin Blackleg Serum Co. in Denver Colorado. The second largest was made by “Ovocol Chem. Co. Brooklyn N.Y.". Smallest one is stamped with “Novol Anestube B”.
