Here is a little information from the Practical Machinist website:

"The Columbian Hardware Company, Cleveland, Ohio also made anvils. In 1926 this company became The Columbian Vise and Mfg. Co. The company made ten sizes of anvils, ranging in size from 10 pounds to 800 pounds. They were very much like the Swedish anvils, being made from electric furnace cast steel. All of their anvils were cast, the face was machined and then hardened, the face was then ground after hardening. All of the Columbian anvils were marked with the letter "C". The company stopped making anvils in 1925."
