Sinar reflex viewer on Graflex Crown Gaphic with Graflok back?

Hi all,
will a Sinar Binocular reflex Viewer fit on a Graflex Crown Gaphic wiith Graflok back?

I currently own a Sinar Binocular reflex Viewer but I do not own or have access to a Graflex Crown Gaphic wiith Graflok back and that is why I am asking.

Thanks

Gary

No it's not a direct fit w/out modifications anyways.

Thank you for your reply.

If you can find a $50 or some such Sinar Norma Auxiliary Standard, you can destruct that and maybe attach it to your Speed Graphic. Maybe there is a way?

Hello everyone, what's the size(dimensions) of the mirror inside the Binocular reflex magnifier?
