Griswold H&S waffle iron

Hello, everyone! I just bought this waffle iron in Craigslist for $8. Maybe I'm crazy because while the waffle maker itself is in good condition, it has no base with it. I need to find one. Question: How do I know what kind of base I need that will fit? I don't even see separate bases on eBay anywhere. Thanks for your help!

Your paddles should have pattern numbers. The table on this page will help you identify which base p/n(s) matches your irons:

So I go by the 919 and 920?

Yep. 4 bases to choose from.
