I went and took a few test shots to try the camera out. It is underexposing a bit and the focus point is just behind what I'm focusing on. I'll make one more tweak and call it good. I tried the looking into the camera with a second camera method followed by looking at the film plane. For my eyes, looking at the film plane was difficult, would work better with a magnifier which I didn't have handy. I used the split prism of the reference camera. In the end, I expect the camera to work fine. I am now going through a rebuild of a Mamiya 1000DTL, same kind of focus screen setup.
