Pipe makers marks
Among pipe makers marks, a logo on the stem can be a company device, but stems can be replaced. A shape number is not automatically a year.
Shank wording and stem logo
Inspect both sides and the underside of the shank for the manufacturer and shape code. A logo on the stem can be a company device, but stems can be replaced. MADE IN ENGLAND or another country phrase is separate from the brand.
What to check next
Record every number with its position and letter style. A shape number is not automatically a year. Compare the finish name, country stamp and stem emblem with the manufacturer’s own marking system.
