Back in 1928, Barling attempted to amend the Merchandise Marks Act revised 1926, so that only pipes fully made in England could be stamped as such. Dunhill led the charge to stop the amendment, saying that it would be a “disaster” were it to pass.Never seen anything to substantiate this. Not saying there weren't periods. But would be news to the folks who show up to work every day at the St Andrews Road factory. Possible they have at times finished stummels from other sources.
Why? Because they and others bought stummels to finish and mount. It was common practice. But, the cachet of “made in England” mattered, and losing the ability to apply that stamp meant lower profits. Dunhill and the others won that battle. To this day, made in England doesn’t guarantee that the pipe was made in England.
The Paris factory isn’t a secret. You’ll find Dunhills with a “Paris” stamp on the shank.
The business about outsourcing to Italy was a secret, one divulged to me by a salesman at the Dunhill store in Beverly Hills back in the early 90’s. It was also interesting to note that the staff wasn’t enthusiastic about the quality of the pipes they were selling.
