For Trade WTT my Voigtlander 40mm Nokton for your Voigtlander 40mm UltronSL-II (nikon mount)

The title mostly says it all. I don't need two 35mm systems so I'd rather keep my Nikon and use a 40mm Ultron on it. My Nokton is in great shape. It's the single-coated version. I think I've got all the stuff, including the shade.

Once I've made a trade I'll probably list my Bessa R2A body.
