As per title, chasing a Bronica S2A Focusing Helicoid, any distance markings for any focal length is fine. Working condition.
Also after a 75mm f2.8 Nikkor for a Bronica S2A (If it's packaged with the helicoid, even better!). User condition is fine.
I'm located in Brisbane, Australia but happy to pay for intl shipping.
Let me know if you have either to offload.
