2) Block letter stamp “Silver S” used until late 1960s and then changed to script.
3) Up until the early 1960s only the top pipes, e.g. “Hand Cut” had the stem/mouthpieces stamped with the Stanwell logo of a crown over “S”. The “Hand Cut” is stamped on the shank of the pipe. The “Standard Models” may or may not be stamped with the “S” logo without the crown.
