You have an 1880's era Fisher anvil. Look under the anvil on the base....there "might" be a date there. Either way, your anvil was made 1879 or 1880. They did not start marking the date under the heel with this model until some time in 1880.
The Cast Steel refers to the horn plate, they were cast steel. Just a marketing thing by F&N. The 119 weight stamp might have been added later. The rest of the stampings are original.
The anvil was made in Trenton, NJ.
