Before I re-invent the wheel and mess about trying to compose my own...

does anyone have a view finder mask for the Adapt a roll for both formats (6x6 and 6x9)?? I just need the dimensions. The 6x6 is at a wierd offset from centre
I can laser cut them out of thin stainless.

I have the Ground Glass cutouts but I prefer to use the viewfinder.

Thanks in advance..
