Hello there
I am currently in the process of updating the pipedia.org list of Stanwell shape numbers throughout its history. The original list was compiled by Basil Stevens, who knew more than anyone outside of Stanwell employees themselves about the brand, but sadly he passed away a few years ago. As Basil's list was compiled based on available information at the time, and through his contacts with other Stanwell collectors, the list was far from exhaustive. Thanks to social media and the various ways in which Stanwell pipes have been catalogued in recent years (smokingpipes.com listings, second-party ebay records, etc.), many Stanwell shapes and lines have turned up which were not on the list. Also, new lines have recently been released, including the latest pipes of the year, the Revival series, and the Favorite series, though these latter two are modified or reproduced shapes from earlier lines.
If there is a specific shape or line you are interested in, please let me know, and I will talk to the Stanwell experts and vendors I know and try to find out more information for you. For now, here is the list I have been working on revising:
