The head is our M8/M9 Converter in10 18 with Torched Oil Quenched finish. (the same base head makes an M9 when assembled with No 9 flanges, or an M8 when assembled with the M8 flanges).
The M8 No 02 Proto Flange and Half Offset Gooseneck shown here are 303 stainless. Attached are photos of the new M8 with No. 02 C flange Proto and the No 02 D flange. The 02 C flange is the same width face to back as the original 02 flange. The No 02 D is approx. 0.200″ wider, and has a larger radius in the heal making it slightly more pear-shaped. There is a light polish on the flange and as-milled finish on the neck. The Logo Medallion is Mokume Gane. Weight as shown is 345 grams, but is customizable and adjustable.
We will have several M8 flange options. Some will have a small cavity so you can see and access the whole medallion, others different alignment features and shapes such as more pear shaped etc., wider, shallower, etc. And of course lots of materials and other custom options.
