Want to Buy WTB: Black Nikon F standard prism

I'm looking to buy a standard stock black prism for the Nikon F. I'm hoping someone may have one of these lying around collecting dust. Some brassing is just fine. I'll also entertain offers for F metering prisms (working or not) such as the FTn, in black if the price is right.

Thank you!

Terry,

KEH has a non-working, but nice looking FTn finder in black for $53. They also have some eyelevel finders for $225 or so. So, there is that option.
