Cast iron flop griddle

This is a cast iron flop griddle. They were sold in the late 1800's.

They were used for making large batches of perfectly shaped pancakes. You would fill the circles with batter, let them cook, "flop" them onto the other side, and refill with batter while the first batch was still cooking.

I'm pretty sure you could cook eggs, hash browns or quesadillas the same way. But they were mostly used for pancakes.

It's too big for an electric stove; These were used on wood stoves, or perhaps outdoors.
