Inon 45 degree Viewfinder for Aquatica Housings

I bought this a couple of years ago to use on my Aquatica housing for my Nikon D7000. Never wound up using it so decided to hopefully find another loving home for it. Here is the original description from whom I bought it from (again I have never used it):  "Works perfect.  Has some tiny scratches near the retaining clip from the time I had nothing but a hex wrench to install the retaining clip.  The scratches are nowhere near where the O-rings seal, not even on the same surface.  The white thing is a little thingy I 3d printed to retain the clip and ball bearings while traveling."

For reference, here is its description on Backscatter: https://www.backscatter.com/Inon-45-Angled-Underwater-Housing-Viewfinder
