Sadly while cleaning this skillet i found a crack but i have a matching sister in the E-tank. Anyhow this skillet has some destinct marks on it as pictured, just wanted to know if anyone knows what foundry or if it is just another mystery skillet. Bottom is marked with an X close to the handle but also has 120 in the middle of the bottom. there are two small dots on the underside of the handle along with two small notches that are repeated on the heat ring close to the handle.
