Because I'm odd, I'm interested in obtaining a nice-looking set (that need not be portable) for Capablanca chess, the third world champion's chess variant which is played on 10 x 8 board and features two new pieces for each side: a chancellor that can move like a rook or a knight, and an archbishop that can move like a bishop or a knight. Is there a place that sells such sets?
I'm recording this answer here because it took me quite a bit of searching to find something, primarily because I never found any sets going under the actual name "Capablanca chess." I did find workable sets under the names "Gothic chess" (apparently because of someone's fairly recent spin-off of Capablanca chess) and "Grand chess" (intended for a 10 x 10 board, see below).
I've only managed to find one 10 x 8 board, this one from House of Staunton. In addition, they have a full set of pieces (including pieces designed to be archbishops and chancellors, with a 3.75" king height) designed to fit the board, so that's at least a working answer to the question. Unfortunately, that piece set runs $200, so an alternative would be nice.
MindSports in the Netherlands has a set of pieces, which they intend for a game they call Grand chess that's to be played on a 10 x 10 board, that would work as a Capablanca chess set; the design of the archbishops and chancellors even reflect their movements, as can be seen in this picture (f- and g-files):
That set costs a more reasonable $40, but features a 3" king, and so that set would unfortunately be out of proportion on the only 10 x 8 board I've found (the one above). If you're happy to use a 10 x 10 board (and ignore part of it for Capablanca chess), then this is one way to go.
From what I know now, the best alternative to the $200 set above for use on the 10 x 8 board would be the House of Staunton's plastic piece set for Seirawan chess. This set runs only $40, has a 3.75" king height, and has a Hawk and Elephant piece for each side,
which can be used to represent the chancellors and archbishops of Capablanca chess.
