For Trade Vintage S M camera cases, Japan, unknown company? Medium format?

[Clicker]

Ken below has informed me that these are Mamiya cases, Thanks!

These are marked with a logo, " S M", and marked made in Japan.
Other than that, I know nothing else. If you know, feel free to comment!

Case one, sort of a half dome shape is 7" x 4" x 3.5", has strap loops in the back, good condition, inside is felt lined

Case two is two parts, openings for knobs, some wear on the leather in places. 8" x 6" x 3.5" See followup for images (I messed up)
All snaps work. Red felt inside lining, but not on the sides.

I'm guessing $25 for both plus shipping.
Shipping $10
I will ship worldwide for actual postage.

The side view in your center image looks like a case for a eye-level prism from a Mamiya TLR. I have the glass prism for a Mamiya C330S TLR and the case looks nearly (but not exactly) identical. The displayed logo is definitely Mamiya.
