I have seen a full size set stamped Miller Browne London and Boosey & Hawkes, London. These looked like low end Starcks, plain turned, made from a reddish brown Brazilwood, and with appallingly cheap looking ferrules, soldered together at one time but now all split. I had some pictures of this set, but unfortunately I lost practically all of 20 odd years of vintage/antique pipe photos in a computer crash a year ago. I have not seen any Starcks made from such low quality wood or with such poor fittings.
They definitely supplied higher quality pipes, a guy in Creiff was selling a very nice AWB all ivory set stamped Miller Browne London with an MOD arrow and dated 1956. These looked very much like Starcks.
I also saw a Brian Boru set reputed to be Miller Brownes, but only stamped with the H. Potter mark. These were also made from a reddish brown Brazilwood, but with the heavy all over beading that Starck used to use on his “Irish” pipes instead of beading & combing. It had a common stock, where it was stamped. Once again, it had very cheap looking ferrules, soldered together at one point but now splitting. I would have said “Starcks” but for the cheaper wood and poor quality/cheap fittings. I usually associate the Starck name with quality.
The conjecture was that it may have been made for the Irish Guards, who were based in Aldershot.”
