Update for all
I know this thread is old, but wanted to give some update on it.
The product is a Tramontina product: w3: tramontina-usa.com/global_innovations.pdf (shows the product)
You can actually tell the difference, simply by sight, between the simular Calphalon product by the lid handles (Calphalon=flat-stamped, Tramontian=smooth) and also the number of long-handle rivets (Calphalon=3, Tramontina=2).
I've also seen the same picture which is used on the Sam'sClub page, also used in an Tramontina add on ChefDepot.com: w3: chefdepot.net/stockpots2.htm
(however, not sure of the ligitimacy of ChefDepot)
