Found the one in the first pic!

I was at a swap meet here in the area today and "The right stuff brake" folks had a table set up, bought the stainless steel version which as you see in the first pic is shiny enough to see reflection.... $20 works for me.
Besides the real nice one in the 2nd & 3rd pic I found out is of a home made one, compliments to the maker!
