Looking at the wall thicknes and milling of the surfaces that stuff is very interesting.

My favorite pan is a well used Erie that is not a collectors item because of the wear but boy is that relatively light!

I would like to hold one of them in my hand before spending that much money but if you look at the price of a collectible/vintage piece and compare it then they are not that much out of line.

P.S. That Erie I mention although it is showing its age is around 150 years old.
