Minicam Flash for Mamiya Press Super 23 or Universal cameras

[gordrob]

I have a Minicam Bulb Flash handle that is missing the reflector. The flash unit was made specifically for the Mamiya Press Super 23 or Universal cameras. I have had no luck in finding out what kind of reflector the handle used. There is no mounting flanges or the like to hold the reflector in place. I am hoping someone is familiar with this unit and can shed some light on it for me.

This may help a bit. Can't quite see how it fits though.
