Lead n Brass
I have dealt with several antique Chas Schenk copper pots my concerns would be as follows. Are all the seams sweated/soldered, why did it not possess more patina if left exposed in a landfill? and lastly is it or any part of it magnetic I see the hamered rivets which is a good thing, but I wouldnt dismiss it may have been brought back from overseas. I witnessed many shops making very good looking handmade brass and copper wares.
Either way a very good looking pot and definitely a keeper.
