Looking forward to sharing all of your cast iron info. My first iron pieces were three older Wagner skillets, given to me in the 1960s. A stint on the East coast in the 1970s led me to flea-market finds: a three-legged bulge pot, a gem pan, a corn muffin pan. Have bought some new pieces, but the old ones are my mainstays for everyday cooking and camping. (The bulge pot also goes camping with me - great for campfire chili.) My 4-3-4 gem pan is unlike any for which I've seen photos, with wide, flat, sturdy end handles, and has no makers marks. It has a sprue mark in the center cup.
