Cool Cobb, Leon, and a nice addition to the collection!
With regards to the original post, I've only seen T3s showing grey borders with any frequency, and that seems to be the natural, intended color. Maybe the beige versions are just faded examples? Maybe it's the way T3s "tone" or react to humidity? Wish I could give more info, but at least I'll give the topic a *bump*
Conor, you might also try sending a PM to
Craig to get his take. Not only a nice guy, Craig's also handled quite a few T3s.
