The inside of the lid is stamped r. I believe this piece to be from norwich, england in the county town of norfolk, england. I believe this piece is circa mid to late 1800's.I decided to not clean, polish and restore this piece due to having the beautiful original patina still intact. Some people like it and some people don't like it.
If you wish to do so though, with a little elbow grease and ketchup it should clean up very easily and nice piece measures 16 tall, 15 long with spout, and 14 wide with handles. Due to the age of the item, i consider this piece to be a decorative item only. I can not guarantee any functionality of this piece due to deterioration of internal parts and seals in the spout, handles, etc.
If you have any other questions please feel free to ask thank you. This item is made of metal.
