@Craig - So about the lid.....It looks like there was some sort of logo on it at some point that caused that area to not fade as much as the rest of the lid. Appears to be a cupcake, mushroom, or chefs hat, or at least that is what I make of it. Interested to see if the darker spot is what you are hinting at and what the story is behind it.
Also, thanks Brian for making what appears to be such a lopsided trade! My wife kept saying, "I can't believe you traded that dinky little red grill [Red Wood Dale 18] for this huge one [a copper mist Imperial Sequoia]." She's probably right.
@Craig this photo reminds me we had discussed the variation in the radius of the inner triangle rods a while back. This one has the large radius type vs. the more typical tight radius we see today. Was a conclusion arrived at that anchors one or the other to a particular year(s)? Also wondering about the strap handles on the bowl vs. the molded lid handle. When did that transition occur?
