Which reflex viewer to fit international backs?

Can anyone definitively tell me which reflex viewers will fit an 4x5 international back?

The International Back definites the sizes and distances so one can use international film holders. The other side of the ground-glass differs from camera to camera. So look for a reflex viewer made for your camera.

I've found the info I've been looking for.

The international back is a Cambo product. The international revolving back is a GREAT back and the reflex viewer that fits it is the Cambo brand.

The revolving Cambo viewer is a great item and it weighs next to nothing. It is bulky however.
