The Lawton-Barton mouthpieces and the earliest Lawtons in the mid 1960s had slightly different markings on them that are described and shown on the pages devoted to those vintage models.

Since 1967 Lawton mouthpieces have been stamped on the side with markings that identify the maker’s name, the tip opening, the model and/or variant and sometimes the material.

Looking from the player’s perspective, the following information is stamped on the left side with a space between each part:

• Maker’s Name: “LAWTON”

• Tip Opening code: e.g. “7” or “7 STAR”

• Chamber Model: no mark for the Plain (Standard) Model, “B” or “BB” or “BBB”

• Variant code (if relevant): e.g. “R” for Reflector baffle, “S” for “High Resonance chamber”, “LW” for Long Window

For some models additional information might also be stamped on the right side:

• Material: e.g. “SPECIAL” or “BRONZE” where the common models are made of Bell-Bronze

• Special edition name: e.g. “ICON”

The end of the ligature thumb screw has lettering around the circumference: “LAWTON MOUTHPIECES ENGLAND”.

From 1967 Lawton mouthpieces were stamped with lettering approximately 2mm in height for all saxophone sizes (baritone, tenor, alto and soprano) and all materials. This was the letter size that appeared in the pictures in the original Lawton leaflet in 1967 and the same leaflet pictures continued to be used even as the lettering size on mouthpieces changed over time.

The following lettering sizes have been used:

• Small (original): 2mm height and stamped deeply, “LAWTON” approximately 11.5mm long

• Medium: 2.2mm height and shallower / finer, “LAWTON” approximately 13mm long

• Large: 2.7mm height, “LAWTON” approximately 16mm long

A letter height of approximately 1.5mm seems to have been used on the ligatures for all saxophone sizes and at all periods of production.
