Want to Buy Graflex Graphic View glass protector/shade

I'm looking for the removable ground glass protector and shade from a Graflex Graphic View or Graphic View II:

The piece I need is the inner rectangle in this picture:



The piece is hinged at the top, and a release button at the bottom. I've seen them in grey and black. I'll take what I can find, but I'm looking for clean shape, and prefer grey.

I have one if you haven't found one.
