Want to Buy WTB: front shift locking screw for Wista Metal Field camera

Hi all,

As I explained in a little more detail in my (there was a url link here which no longer exists), I'm after the double threaded screw used to lock the shift on the front standard of a Wista Metal Field. If anyone has any parts from these cameras, or any junkers lying around, I'd love to hear from you.

Cheers,
Steve
