Hassy mask for A16 back

I would like a mask for the A16 back I have but can only guess at the frameing. I image it is a 645 format, and wondered since I can not find anyone selling the mask if someone would trace one and upload a scan of the layout. I imigine I could do a simple overlay and drop it into the WLF. Any ideas?

If you're in the US, KEH has them sometimes.
The alternative I prefer is a focusing screen with the grid, but that is more expense, especially if you use an Acute Matte screen

A simple, free, but not totally precise solution I use to know crops for common vertical page and for horizontal double page crops is to measure and mark the ground glass with a permanent marker.

I don't draw a whole line across like a gridded ground glass, but just small lines notching in that are visible but not obtrusive. Easily ignorable, but if I need a reference they're there. It might not be precise enough for some, but if you take your time measuring the notches are pretty accurate to whatever crop you might need.
