What is this???

G'day everyone!

This has popped up in my local classifieds and I can't for the life of me figure out what it is...

Obviously the hood is a hood, but can anyone guess what it belongs to?

And what's the other 'thing'?

I feel like I should know the brand logo, but can't place it...

Looks like a lens hood and a VF diopter mount for a Japanese TLR camera.

Huh, I've never heard of such a thing...

the hood is definitely for a Mamiya TLR lens, probably the black-shutter 80.
