The Devonshire CC&Rs require that all mailboxes conform to the style as was originally installed for our subdivision. The style of our mailboxes is "The P&P Classic" style, sold by the company Posts & Pickets (also known as More Than A Mailbox. ) They are located off of Tryon Rd. in Cary, NC.
November 2024 update: the style and company described above still exists but the only active site at this time is their Facebook account: https://www.facebook.com/people/Post-and-Pickets/100091997806044/
