Anyhow, I'd like to find the maker of this. I'll let you know when I find out!
Added later: Within minutes of posting my question on Cast Iron Collectors Forums, I got my answer. I didn't get permission to quote, so I'll paraphrase the answer. It is a Griswold and there were 6 variations made, of which this is variation #3.
Two books that list Griswold values put the value at $100-150...but these are considered high. Ebay is considered a good determination. Right now there are five of these listed at $89.99, $128.00, $175.00, and two at $225.00. The current condition of mine makes me think it is worth 89.99.
The forum says either way, I got a steal. Sounds good!
