mamiya tlr prism finder eye cup

[bhaning]

I'm looking for a replacement eye cup for a Mamiya c330 prism finder. The one I have is old and brittle. Does anyone
know where to find a replacement eye cup?

Back in 2006 I called Mamiya at the Manhattan New York City Office and bought the last two that they had. As you just might have heard, I traded everything Mamiya in for Hasselblad equipment shortly after.
