With the sweeping lines and absence of bases, the set reminds me of the Western versions of the Best Chessmen Ever pieces designed by Ifekali. Like the Stage 2 BCE pieces, these have collars.

The BCE Stage 2 pieces. The first image is of the Eastern version...
Last Friday my friend Phil and I pulled out my Chess Bazaar Staunton Series set and played with it on my RCMacMillan Memorial Knock-off board. Although listed at 3.8" for the King, it fit and played extremely well on the 2.5" squares. It's ebonized, one of Chess Bazaar's economy line. I bought it to take to chess club, but as I play mostly in close proximity to my bar and beer fridges, it hasn't seen much use. It's well-weighted, and a little funky. A lot of fun to play ten-minute with.
