Hasselblad PM5 on Mamiya C3: possible?

[anta40]

I found someone selling a Hasselblad PM5 at local online marketplace. And suddenly I remember this: Mamiya C-series adapter for Kiev88/Salyut prism viewfinders.

Unfortunately, I don't have the finder so couldn't try it.
Makes me wonder: is it possible to adapt the PM5 on the Mamiya C3? Perhaps someone on this board already succesfully did it?

I bought a 3D-printed adapter to fit a Kiev/Hasselblad prism on a C330.
It didn't quite work, the mounting grooves were too high in the adapter and the material used didn't want to play nicely with my Dremel tool.

Hmm is the link still available?
Putting the PM5 on the C3 is a seriously tempting idea, at least much affordable then buying a Hassy kit

This is the official prism finder for Mamiya C TLRs, I guess?

I asked a friend who is doing custom metal works to modify the hood of my Mamiya C330 to hold a Hasselblad PM45 finder. the modification was quite straight forward, it's a bit fragile but works very well.

That is not a prism. It employs mirrors instead, and gives you a reversed image.
You can see the prism - along with yours truly - in this self portrait:

I cut a few strips of Grey Gaffer Tape to hold the Hood tightly down. Raising it with the Adapter will provide a bit better viewpoint. But Hey it works!

I handmade this kind of adapter of a Kiev 60 metering prism for my Rolleiflex T : metering works (uncoupled, of course)

Ah I see. Seems like finding the prism alone will not be that easy....

No - it was a readily available accessory for a long time.
However, finding one that the owner wants to sell may be more difficult - they are quite nice to use, if somewhat heavy.
I bought mine used from a camera store many, many years ago.
When I used the C330 for wedding photography, the prism finder was on almost always. Weddings aren't well suited to the "navel eyed" view of the world that a waist level finder encourages.
