It's real and Grabow used it and others did I'm sure. Here's an excerpt of something Tom Douglas, former Grabow president, wrote to me. There is more out there, but I'd have to hunt for a while.

Some stems are made with lower grade Vulcanite that oxidizes faster due to sulphur content, and some people have a body chemistry that seems to oxidize them. I have had pipes where the stem starts oxidation from just one use and currently have pipes where the stem has never shown a trace despite years of use. I've always preferred Vulcanite but have taken to Cumberland type stock, colored Ebonite, almost specifically. All the comfort of Vulcanite with a splash of color and they appear more resistant to oxidizing.
"The bulldog has a German bit which is almost indestructable. In the late 30's Hitler wanted a material for vehicle tires and tank tread. One was made from vulcanite and a plastic of the day. Didn't work for vehicles because it was so hard that a light rain was like ice. Tank tread just busted off.
Some genius started making pipe stems from it and they are fantastic. Never oxadize, will barely mark. Wish I had a hundred more, but only 4.. ted"
