Yes, more cast iron. It's officially an obsession. :-)
This is a Griswold #9 griddle, made sometime between 1925 and 1940. It has a cooking surface diameter of 10.5 inches. This pan was thrown in for FREE when I bought a dutch oven at an antique store here in town. (I don't know how I came away with two more pieces of iron... I just went in to look, honest...)
It's in GREAT condition. There was a bit of rust on the bottom side, which easily cleaned up with some vinegar and steel wool. It left a very small amount of pitting, but as you can see from the photo above, it's barely noticeable.
The cooking surface is completely unblemished. Look at how smooth it is!
I've never owned a griddle before, and I love it. It's great for things that need to be flipped, since there aren't any sides to obstruct access with a spatula. All I want to do is cook pancakes now!
