How about a Downton Abbey DVD box set or a book about the making of the show? He might also enjoy a Downton Abbey themed tour or an experience of high tea like they have in the show. If he enjoys cooking, you could give him a cookbook with recipes inspired by the show. Or, if he's more of a fashion enthusiast, you could get him a pocket square or ascot inspired by the show's Edwardian era wardrobes. Finally, you could consider a framed photo of the two of you in front of Highclere Castle, where the show was filmed.
Or you can get him a star map with the date of your first kiss.
