While the timing and exact nature of the early relationship remains a bit of mystery, Parker was destined to eventually merge with Hardcastle when in 1935 Dunhill opened a new pipe factory next door to Hardcastle, and purchased 49% of the company shares in 1936. In 1946, the remaining shares of Hardcastle were obtained, but it was not until 1967 when Parker-Hardcastle Limited was formed.
It is evident through the Dunhill factory stamp logs that Parker and Dunhill were closely linked at the factory level through the 1950s, yet it was much more than a few minor flaws that distinguishing the two brands. Most Dunhill "failings" would have been graded out after the bowl turning process exposed unacceptable flaws. This was prior to stoving, curing, carving, bit work and finishing. In others words, very few Parkers would be subjected to the same rigorous processes and care as pipes destined to become Dunhills. Only those that somehow made it to the end finishing process before becoming "failings" enjoy significant Dunhill characteristics, and this likely represents very few Parker pipes.
After the war, and especially after the mid 1950s the differences between Parker and Dunhill became even more evident, and with the merger of Parker with Hardcastle Pipe Ltd, in 1967 the Parker pipe must be considered as an independent product. There is no record of Parker ever being marketed by Dunhill either in it's retail catalog or stores.
Parker was a successful pipe in the US market during the 1930s up through the 1950s, at which point it faded from view in the US, while continuing to be popular in the UK. It was re-introduced into the US market in 1991 and is also sold in Europe.
