I.D. this fishing pole

I have no clue. I'm thinking 1875 give or take. Could even be from before the Civil War. About 52 inches in total length. I can find no markings at all. It is in very good shape so it should have at least had a copyright or something. Might be a mark under the line on the spool, but I want to leave the line alone if I can, it is getting a little delicate.
