Want to Buy WTB: Tamron AD-2 Adaptall-2 17mm f/3.5 for Parts

I'm casually looking for a 17/3.5 Tamron for parts to help my copy out a bit. Needs to be the earlier kind with the built in filters.

I have a good front element, could use a nicer rear element and internals potentially. Don't need any Adaptall-2 mounts, all set there.

Please PM me with what you have and what you $$$ need for it.

WTB retracted.
