ITKI,
FWIW, I installed a Rick Oleson screen in my 'Cord Vb, but had to return to the original screen because the focus was off. Rick offers a very nice and bright replacement screen, but be prepared that you may have to send the camera off, with screen, for a focus adjustment; or, perhaps, if you're a mechanical type you could fix yourself with shims. Anyway, I just wanted to pass this info on.
