ode logicalone what is that.....first glance looks like an old r11/rbz adapter but the markings are for the newer/post r11 heads. Likely just the color that's throwing me off, but ??
You are correct Ode! There was a special “LD” adapter for the OG RBZ , R11 etc... line. I gave you 2 degrees of adjustability up and 2 down. I had/ have one in green.
