This is a stainless steel steamer insert.

i am not sure of the maker, but it is very heavy, quality stuff. It does not fit with my revere 3 qt so I think it is a 2 qt. It measures 6" across the bottom, and 7 1/4 across the top.

it seems like it is from a pricer set, as it is very heavy, better than revere.

It doesn't have any name on it, but I took pics of the handle, so hopefully someone will identify it for me.
