Information not reported here strongly indicates that while stop stampings continued after the early 1930s for Root DRs and into the post-WWII period, both the placement of stops and grade system changed dramatically. In light of some inquiries and loose remarks on eBay, it should also be noted that while one often sees stop stampings with standard Bruyeres (i.e. non DRs) of the 1910s and 1920s before either an A or a circled (A) there is no indication from the catalogs that these stops were value indicators. Undoubtedly whether a standard Bruyere pipe during this period was stamped with a circled or uncircled A or followed by a stop was meaningful, but that meaning most probably related to production or distribution concerns as opposed to grading or value.
