According to
Ashton, they are made by Manning of Ireland, who has been making humidors since 1887.
High quality pieces no doubt, but at a starting price of $600 to $800 for a 12 x 9 x 5 ish humidor and at least a grand or more for a 17 x 12 x 7, I'd be talking to Ed over at Waxing Moon and be having an equal or better quality custom humidor built in the size I want, out of the woods I want, with the extras I want, and probably for less money.
