Graniteware coffee pot?

Hi I think this is an enamel ware coffee pot. I am having a hard time finding info on a manufactor or pattern name. Any info would be very welcome. Thank you very much. The pot stands just over 10". The knob on the lid is wooden , turned and black. The lid also has a folded seam. Any ideas on age. I realize these were made for a few centuries. Thank you Barbara. Rexeroll@gmail.com
