You don't normally see a handled griddle of this size!  Not only is it likely over 120 years old, but it has a handle, unlike most griddles of this size.  The maximum size we see a handled griddle is typically a #10 so its very unique.  We have sold both this size and the size 14.  There are raised letters on the bottom (likely NE9) but its difficult to source a foundry. There is some usual sulfur pitting on the bottom from where it was used over a VERY large eyelet on a wood stove and on the cook surface that will not affect cooking.   It moves on glass so best for gas and coil. 
This griddle is perfect for fireside cooking, or making wood fired pizzas, and is an amazingly unique tool for your gourmet kitchen. There are not many of these around so don‘t miss out!
