New briar in places and burl veneer, Cherry chamber tapered from 7/8" to 5/8" at the bottom. Side walls are about 1/4". Plateau shaved off. Original ferrule is under the veneer. Used JB Weld. Handles 600 degrees. No glue anywhere near tobacco. No thin briar anywhere. Pipe is the original full size freejand type, about 5" in length. Might go for another 50 years!

Happy Thanksgiving!
