Lower Film Spool Knob for Mamiya C330 TLR

Need part for Mamiya C330 TLR

I'm trying to find a part from my camera and not having very much luck. I sure hope someone here can help me.

The lower film spool knob is broken off of the camera. So, I guess I'm looking for the part, a parts camera or advice on what to do.

I have included an image of the broken part and where it came off the camera.

Thanks for any help you can provide!

There was a C220 body trashed floating around here, or craigslist in Washington or Oregon for cheap. Sorry I can't remember where I saw it. Wonder if it has something usable?
