This griddle was acquired from great grandmother who was born in 1881--not sure if she was original owner. The griddle is 9.25" diameter, handle to griddle top is 13.25". On the back the heat ring is 7 3/8" diameter with a rounded notch at 2:30. The raised molder's mark "8" on the bottom at 6:00 is the only marking. I have been unable to locate one like this with the handle hole pointed at both ends. The handle by the hole is flat on the back--see pics. I would appreciate any information. Thank you.
