I need some help identifying a cast iron waffle iron I just scored at a yard sale. The previous owner let it get pretty rusty, and I've already hit it with the wire brush but I honestly haven't made much progress. I'm not seeing any markings, like no numbers, no letters, nothing just yet. I probably need to also ask tips what's the best way to clean and restore this one but I'm really more curious to know if I found a special one! The plates are a perfect 7" by 6.5" square. Any ideas what I might have here? Thanks in advance for any info!
