I believe Brylon was discontinued in production fairly recently like maybe 2018. After I wrote this original post, I believe I read a history of Brylon that said it was introduced in the 1960's, not the fifties. Online retailers that used to offer them no longer have them in inventory, though perhaps they pop up from time to time. I think Dr. Grabow still sells The Pipe, which is a synthetic but not Brylon, if I have it right.
I had two The Pipes when I was in college & din't know no better. The only thing I'd use those for now would be to test out blowtorches. Not even the "boat anchor" option any more. I have never in my life had to puff a Brylon, & absent the influence of Satan I never will!
