I'm selling a Model 01 that I bought a while back, and haven't used much. The ring anchor isn't really want I wanted and after trying to deal with the company to get different parts, I decided to just sell this instead. The finish and craftsmanship is great. The ring anchor will take larger than 6ga rings for sure. I've had a 2ga ring in it just fine. Sizing: Ring - 50mm Cage Diameter - 37mm Cage Length - 44mm Hook Thickness - 6ga Hook Type - Ring Anchor Security Seal Hole - Yes I'm asking $225 shipped.
