What is this for? A burger-press? I've &quot;inherited&quot; this thing a long time ago, and I have no idea what it is. It consists of a cylindrical porcelain bowl with the words &quot;Mason Cash England&quot; stamped in the bottom, a very sturdy cast-iron frame with a screw through and two circular discs of zinc-plated iron that fit neatly inside. I could half imagine it being use to produce a perfectly circular burger, but it seems like absurd overkill. Here's a couple of pictures:


What is it actually for - anything to do with cookery at all?
It appears to be a 'Meat/Cheese Press':

I'm not sure why you'd press meat, but you'd use it with cheese to press the whey out.
