Owned by Dunhill. Depending on who you listen to, Hardcastle is either a Dunhill second or a Parker second (making it a Dunhill "third").
I had a Hardcastle prince a few years ago. I picked it up for a few dollars as an estate, and sold it a year later for what I paid for it. It was an OK pipe; not bad, not great. Better than Grabow, probably on par with Peterson.
I like the look of the Crescent Rustic finish. IMHO it looks like a nice, simple, standard English pipe.
