I purchase the last piece original WEHE adapter $145 from prof.Roberts Ketzner in 1993, I still use the original WEHE mount myself, since the adapter will not seen anymore,  I reproduce the very similar WEHE adapter again, this solid metal adapter will exactly as original fit all the WE mount adapter for Hasselblad 2000. I also lower price to very reasonable level to all WE user.

Since I use kilfitt lenses more than 20 years, I spent lots of time learning from Ketzner  files about kilfitt lenses and adapters, if anyone has question may discuss with me.
