I just have a few points to add at this quite late date. The genealogy of Ben Wade is confusing more than usual even in the often merging pipe world! That said, I believe I have some definitive conclusions. BW started in Leeds, England, in 1861, where it remained until three years after Lane Ltd. acquired it and Charatan in 1962. In 1965, Lane closed the Leeds factory forever, ending not only the famous Made in Leeds England, or just Leeds - England nomenclature but relegating the great hand-made century-old brand to machined seconds! a great brouhaha among connoisseurs has ensued ever since as to the quality of these machine made BWs, and rightly so, if simply because with any pipes made completely by factory assembly line, there will be fills and other blemishes that the hand craftsman's eagle eyes will catch and reject. Also, the shapes became mere classics in many instances without their old flair; the finish was heavy to cover the flaws and of course not as well applied, and the over-all finished product was often not all that appealing -- compared to the magnificent old specimens! But while I've owned some awesome old hand-made beauties that without doubt exceeded the quality of the Lane versions, I've also found still more estate Lane seconds that I cleaned up, restored (perhaps to conditions better than they ever looked in the first place) and found to be engineered soundly and producing an excellent quality of flavor and other results the discerning pipe man seeks: long-lasting, cool, dry burning to a fine ash at the bottom of the chamber included. And by well engineered, I mean they passed the first test of passing a cleaner from the button of the stem into the bottom of the chamber while the two parts are connected. My personal favorite BW period was the Preben Holm freehand collaboration that Lane, for purely financial gain, approved and then pulled the plug when Holm's personal financial difficulties returned due in part to difficulties with the U.S. market. At some point, Dunhill got its hands on BW, until Peter Duncan of Duncan Briars fame bought order rights in 1989 and literally saved the day once more. Therefore, Ben Wade pipes are again, it would appear, being made with still better quality at the Hardcastle plant of Dunhill -- for Duncan!
God save the Duncan!
There are other sources that can be cobbled together piece by piece, but here is the best:
