I need the threaded round disk (T thread) for the front of a Vivitar Universal Bellows. This is the threaded plate that a female T adapter (allowing use of a standard camera mount lens.)
The threaded round plate is held in place on the front of a Vivitar bellows with 2 locking chrome thumb screws.
I DON'T need or want the common male threaded adapter (to adapt a T mount lens to a camera). I have most of the other Vivitar bellows accessories (macro stand, focus rail etc.)
As it is, I have no way to mount a lens on the front of the be(llows.
I have several female T adapters, but not the threaded disk they screw into.
Would consider a "junker" bellows having the threaded front plate.
Thanks for looking.
Bob.
