I bought it around 40 yrs ago at a flea market - obviously used. The interior was well-seasoned but there was a little rust on the exterior. It's 4 qts, with a loop handle like a bucket, and a little ear on the middle of the rim on one side, to hold onto while pouring out the contents. The inside of the lid has 2 concentric circles of nubbins for directing the dripping of the condensation. The only thing on the exterior bottom is an 8, stamped into it near the edge. Can any of the cookware mavens on CH tell me its age or maker?
