There are two kinds of Vernon fitment: one was attached to the shank and other to the mouthpiece (Dunhill would have made the switch to the stem side because the wood being softer than vulcanite and more prone to wear).

Il y a deux sortes de dispositifs Vernon : l'un était attaché à la tige et l'autre au tuyau (Dunhill aurait fini par opter pour  le côté  tuyau car le bois était plus tendre et plus enclin à s'encrasser). Ainsi le brevet anglais fut enregistré le 7 avril 1931 sous le numéro 10225/31. Il fut utilisé ensuite immédiatement avec un brevet provisoire (Prov. Prot. N°:10225/31 confirmé avec le brevet final Nº: 363582 du 24 Décembre 1931). Le  brevet était ici enregistré pour un dispositif attaché au tuyau. Il en va de même pour le brevet Américain No. 1861910.
So, British record as 10225/31 on 7 April '31. Applied right after with provisional patent protection (Prov. Prot. N°:10225/31 and granted with final Nº: 363582 on 24 December 1931). In such a case, the patent record appointed a device attached to the mouthpiece. The same goes for the American patent No. 1861910.
      
However, there is another patent that has also been applied to pipes with the same device, patent No. 358812. After researching this patent, I found a record that corresponds to the number but referring to another technology: "Improvements in and relating to pyrophoric lighters", being associated with Dunhill lighter technology (applied in the same period as the pipe fitment). Vernon Dunhill was involved with developing the first mechanical Dunhill lighter, so his association in both cases makes sense. The dates and period of use match. The two tenons and patents were used from the early 1930s up to  mid-1936. Both used, without considering the installation of the device - i.e, the patents can be found in both cases.
