Want to Buy Found: Mamiya RB67 WLF

Found.

I'm looking to purchase a WLF for a RB67. Prefer the newer version with clean glass. Mechanically working but some missing paint is fine. I can either buy it or trade for a chimney finder. I'm in the US.

I have 2 RB67 WLF's, both are in very good condition. I must confess that I don't know how to tell if they are the new version.
