FS: Nauticam N120 Macro Port 87 & Extension Ring 30

I'm selling a couple of spare pieces of Nauticam gear, both in excellent condition:

• Nauticam Macro Port 87 (18702): Somehow I ended up with two of these and only need one. It works with my Nikon 105mm macro lens (and others). Retail: $571, on sale for $325.
• Nauticam Extension Ring 30 (21130): I don't need this ring for any of my current lenses or ports. Retail: $422, on sale for $275. 

Happy to ship anywhere at cost from ZIP code 93924.

These items are still available and now listed on eBay:
