What film are you using?
To be honest, they all look over-exposed to me. The effect is just more
catastrophic in sunny conditions. Have you got a light meter you can
test it against.
It's not the non-Hg cell that's the problem here. Worst case it'd be 1/3
stop out or so. Even a 1.55V cell wouldn't give results like this --
they're about 1-1.5 stops out. I'd hazard that these are 4-6 stops out.
I think that, assuming you have set the film speed right, there's
something seriously wrong with the camera, either in the light meter or
the shutter speeds or aperture linkage, or something.
