OK, looking for info on my strange antique percolator

This is a neat old percolator I recently purchased at auction. There are no marks on it to give me any indication of where or when it was made. The metal base was made to sit on the stove top, "avoiding" direct contact between the stove and the porcelain pot . It appears to be commercially made, but I doubt it had a long life, as there is no typical coffee staining and the cracks were probably from overheating after a few brews! On the third picture, water would enter on the open side of the base and enter the tube through a small hole. Heat from the post, would cause the water to go up the tube an percolate the coffee. Any info on this pot is appreciated as I have searched the web and have not found anything remotely like it.
