35mm summicron coded mount

[Fraser]

anyone know of a good source for a coded lens mount for a 35mm summicron v4, I bought my other coded mount for my other lenses from jinfinance but they don't seem to sell them anymore tried another company on e*ay but it didn't fit wrong holes in the wrong places!
Cheers.

I coded my mount myself. All you need are the black ones, and as it turned out I needed to remove one screw, grind about 1mm on either side of the hole, then replace the screw and paint the whole shebang flat black. Has worked since my days with the M8.
