I was wondering if anyone could identify the name of this chess piece design, or possibly the name of its designer? It's obviously not the standard Staunton set.
Although it is not exact match, the style of your set aligns with what is called the St. George style. Compare your set to this image from the Staunton chess set Wikipedia. An article on chess-museum.com provides more information about this style.
In comparison to your image, the kings, bishops, queens and pawns builds are extremely similar. The rooks and knights are not exact nor are the dimensions the same. I suspect that you have either a variation or a modernized design of the St. George style. Perhaps it is a mesh with the Staunton style.
