Club Aluminum 1/2 pots

[thetammie]

I found a set of Club Hammered Aluminum Pots that put together form a round pan. They can be used separately or together. They look as though they are 2 quarts each. I can't find any information specifically on these pots, I am not sure what they are called.
They are half moon shaped pots with handles.
Does anyone have any ideas where to find info on these pots?
