Now this may sound like another of my daft questions but is there any reason I can't get my local glass merchant to make me up a ground glass focusiing screen for my RZ67 and Toyo 4x5 cameras?
Not sure about the mamiya but I have made a few for my 5x4..

Its really easy and works quite well but not as good as some of the proper ones.
What do you need for the RZ? I have a RB screen where the alignment "ants" have gone for a wander. Like this when I bought it, I suspect they are waterslide transfers and someone has been a bit OTT with cleaning the viewfinder and got it wet.
I haven't a clue what the viewfinder differences are between the RB and the RZ, but if you've a RZ viewfinder with a cracked screen you might be able to extract the glass from my spare RB screen and drop it into the frame. I've since bought a grid screen, so I've no use for the "wandering ants" screen.
I'll measure up in the mornng..

Just as soon as I find the box it's in.. I know what it looks like, just not where I put it.. ..
Found it..
Taking the "glass" out of the frame, which in itself has answered a few questions, the dimensions are:
68mm x 78mm
It's composed of two layers, a lower frosted acrylic screen and an upper glass screen. The "wandering ants" are indeed water transfers on the underside of the glass screen, sandwiched between it and the frosted plastic screen.
