This antique cast iron parlor stove is a rare find for collectors and enthusiasts alike. PP Stewart was an inventor of cookstones and religious articles so I believe this is either a stove top humidifier video or something having to do with the church such as an urn or vessel for holy water. It is rare to find this piece with all pieces intact and very rare to find it with the cover. Even though it is quite rusty, all the pieces are in great shape for the age. The bottom has a chip as displayed in the pictures. Get a neat piece from the 19th century.
