...looks like the tin may have had a paper label?
Great info from Bacco too, the Robinson stuff does seem to be exceedingly rare.
I did read that just before the '34 takeover by Gallaher, that Robinson had acquired both Illingworth and Pattreiouex.
Here's an interesting patent they registered for making roll and twist,

On googlebooks I found an account from 1890 detailing a reference about a chemist procuring tonquin beans for Robinson. Tonka beans had long been used by snufftakers (keeping a bean in their snuffbox) as well as manufacturers, but also used as a flavoring for pipe tobacco, it's still in use today for such, most famously by Samuel Gawith,

...and goes to a theory of mine about the distinct UK flavorings which seem to be somewhat unique unto themselves, and how possibly many of the tastes could have been crossover from traditional snuff scents/additives?
Also found a '28-'32 price-per-lb list which is interesting because King Lud is listed, seemingly indicating that it was somewhat popular?
