I’m sure some of them went to the archery team. Some other pairs went to other athletes. I suspect it was a test to see if a frame coating of that nature would work, but it ultimately failed for consumer use. As you know, the coating is paper-like and very fragile; it would not hold up to many lens changes or even sweat/oils from regular use. There are other models with the same snakeskin-like covering such as the Blade. Other colours, too.
banarno has the red snakeskin M Frame in his collection.
