Stainless will look like allclad inside and you should see the remnants of fine concentric polishing marks. Tin is very shiny when new dull when older. You should see remnants of brush marks. The tin is brushed on and does look like old painted wood. The surface of tin tends to be a little uneven. On older pots you may even see a little copper peaking through. Maviel used to just say made in france...any markings? The brass handles were usually used on lighter pans, the heavier pans have wrought iron handles. The older tinned pans I have use copper rivets, the picture looks like steel but could just be glare.
Everywhere you go, there you are.
I had to go back anyways to return something. I picked up the three pots and some cool old tarnished italian silver spoons.
Thanks for the tips and I'll report back with better pics in a day.
daughter and classmates working in the white elephant booth at their high school carnival saw people relocating items and not buying anything so the students talked to the advisor on duty.
students were told people find stuff they want but do not want to pay the price for that day so the items are "relocated" and, hopefully they can retrieve the items and buy on the day when everything is on sale at clear-out prices.
