It's always worth keeping an eye out for Dunhill pipes with a "3" or "4" as the second digit (which denotes stem style) in their shape stamping. While there are some Dunhill designs that commonly feature either of these numbers (it's standard for the "21" Zulu, for example), often they accompany rather novel variations, and in some cases, downright rarities. This "4405" falls firmly into the latter category - this is but the third time we've ever seen an "x
405" Dublin variant in any Group size.
