Probably a brand of Pioneer Pipes Co., a Meerschaum and Meerschaum lined pipes manufacturer and distributor.

Address (about 1960): 1817 Putnam Avenue, Brooklyn 27, N.Y.

Pioneer also used to import meerschaum pipes from the MANXMAN PIPES Ltd factory (Isle of Man, UK) as shown by the markings of this pipe. (See "Man")

Wilczak & Colwell, op. cit. mention pipes with this label from Duncan Briars Ltd, Oppenheimer Pipes or Delacour Brothers.

Brand created in 1943. The shop (Danish name: Pibe-Dan) which closed in 1991 was run by H. Dan Christensen. He sometimes designed pipes but he is merely renowned for having helped young artisans like Tom Eltang, Preben Holm, Jes Phillip Vigen, Hans Hartmann...

Pipe-Dan let the pipe maker stamp his own name on a pipe along with the shop’s name.
The line name "Shape-Reformed" means that a traditional shape had been redesigned.

Artisan: André Bourgeois † (1911-1983)
Workshop (closed): 16 Rue du plan du Moulin (under the bridge) St Claude (France). All the tools were driven by a paddle wheel. The device has been condamned after the sewage liquids reorganisation by the township.
