What kind of info were you looking for? I mean, Tinder Box has been selling their branded and unbranded pipes for forty years. There's a lot of history there.

My research shows them to be made by Charatan for Tinderbox c1970's. If you google Tinderbox Unique OTC you will see the site that I found. Probably a dang good pipe for the price.
Is it stamped "Unique"? If so, it was probably made by GBD. I was just reading Hackers 1984 book "The Ultimate Pipe Book" and he mentions several UK brands who made pipes for The Tinder Box (and some Italians as well if memory serves).
