If you go to Bergie's (KB) area here, you will see his Birkin listings. I bought this almost a year ago so I dont know what he would want for it right now. Here's Bergie's area ----- http://www.rwg.cc/forum/127-bergies/
Also remember that KB is a small shop, and does not have a huge gallery of photos for items he can supply .. it's only a small sample. It's always best to ask him and he will research for you, and tell you if he can source something .. like that So Kelly Clemence in Ebene Togo leather I bought for my daughter, above ... not listed but he could source it.
edit: I looked in Bergie's area, and I see his calf leather Birkin is $280, and the Crocodile bags are $380
Hey Ken, this Kelly 22cm Clemence is such a beautiful bag, you should add it to your Birkin photo gallery!
