[note, this is a ‘problem’ piece. The date code stamping (pictured earlier) is quite distinct, so should be no questions there, but just as clearly the ‘D’ is without tails, & the subscript after the ‘A’ is a square not a circle. My suspicion is that (i) this pipe was manufactured and initially stamped in 1920 prior to the introduction of ‘tails’ in November of that year, but (ii) that the pipe had not been sold when the 1921 guarantee went into effect, so (iii) the pipe was then given a date code stamp (note that we see this type of additional post production date stamping in later years). I attribute the subscript square rather then a circle to being a transition from no subscript to a subscript circle.]
