vintage French copper pan, very heavy saucepan w/ iron handle, thick wall solid copper

VERY HEAVY thick walled solid copper pan with iron handle, tinned interior. This looks to me like a Dehillerin pan, but I've looked very carefully and I just can't find any markings at all. It's almost certainly made in France, just has that look, that feel, that professional chef's quality!

This is 7" across the rim of the pan, 2 1/2" deep. This is very thick (see photos where I tried to show you the wall of the pan). It's heavy, weighs almost 4 pounds (3 lbs 13 oz) though of course part of that is the iron handle which is also heavy weight.

This is very tarnished, and also shows some wear from use (some scratching to the interior and exterior of the pan). It'll be a beauty once it's been cleaned up and given a good polish.
