I will have to check. I think I do. Also, if you are interested in longer focal lengths, see my for sale post for the Komura 500mm and 300mm lens with the Helical Unit II. They were made for the Bronica S2A. Jon
I have a focusing helicoid for the Bronica EC and I'm sure it will fit the S2A. I have no need of it so you can have it for shipping cost. Contact me and we can work out the details.
