Want to Buy WTB: Broken, scratched, moldy lenses for Mamiya m645 and random elements

I'm looking for seriously damaged, cheap lenses for a Mamiya M645 to tear apart and put other elements in to make weird, blurry lenses. I'm also looking for random elements to use, preferably with not too long of a focal length. If you have either of these items, please let me know!!

I have an 80mm f2.8 with sticky shutter blades that isn't being used - let me know if you are interested!

I have a scratched up 150 with an oily aperture I think.
