They are definitely not USCF (United States Chess Federation) certified, so they won't be showing up in any tournaments, but they are perfectly and easily playable. I do make a reproduction set of the original 1849 Staunton designs, that has been popular. Here's a couple pics, I make them for 1.75", 2.0", 2.25", and 2.5" squared boards, and these are within USCF specs.
Hand-turned/hand carved from Walnut and Pear, heavily weighted and leather or felt pads on the bottom. The knights are 1-piece unlike even Jacques or HOS have ever done, if fact, Jacques and HOS use subcontractors to make their knights, they are two pieces the base, and the knight head.
In tournaments today, plastic and vinyl are the standard, but many players use wood pieces in tourneys as well. Came within a whisker of having a set used in the championship match of the Phoenix Open last year.
