I would be reluctant to remove the baize or felt. I would guess that somebody with a home metalshop might work wood as well. In the retail marketplace, a leading vendor like House of Staunton will offer "generic" caskets which accommodate a range of Staunton-style sets (and could hold others with similar heights and base diameters). If the recessed areas that hold the pieces are snug fits that appear to be shaped expressly for those pieces, then its doubtless a matched package. Go here – http://www.houseofstaunton.com/house-of-staunton-chess-boxes.html – to see a selection of HoS coffers designed to keep pieces from rubbing and bumping against one another when stored.
It wouldn't surprise me to eventually conclude that it's a one-off. Hobbyists produce countless personalized chess sets and have done so for centuries. After all, the game dates back to the 6th century. The only older living board game is backgammon, which goes back to the 2nd century. There are remote tribes that carve a special set fresh for every chess game! Possibly the broadest division of the chess world is that of collectors versus players. I'm sure that all collectors are also players but the reverse is definitely not the case. FIDE (the World Chess Federation) has over 180 member nations, all of whom subscribe to the specifications of Staunton-style set design. The common chess pieces were designed by Nathaniel Cooke who registered his patent 1 March 1849. His designs (now familiar to the entire world) were inspired by the Parthenon Frieze in the Elgin Marbles, and were considered a highly modernistic design solution to a serious problem in international play. Each country had at least one (and sometimes several) popular chess set designs. Players from one country would often find sets from another country confusing. Much rancor resulted as players argued over which set would be used. By standardizing one pattern for the entire global playing community, all the confusion was obviated.
Your beautiful set would be admired but not allowed in any tournament, as it definitely falls into the category of a collector set. I've attached a JPEG of one side of my Austin Cox set, designed by him for Alcoa in the 60s. My AC set was discovered a few years ago by friends poking around in a yard sale who thought of me when they were told the boxes contained chess pieces. They paid $5 for it! It's the only collector set I own. These AC sets auction between $500 and $600 dollars. Your set seems to my sensibilities to be overall a much more pleasing rendering in the modern art sculpture genre. That said, I really haven't a clue as to how to value it.
