If I recall correctly, Huntsman used only CB for their RTW suits that were (are?) sold in their Savile Row shop.
You don't recall correctly; I have 3 Huntsman/Chester Barrie RTW suits that were sold at Barney's in NYC. Also, Manton, I have a Chester Barrie for Burberry odd jacket (purchased in London) that has a wool & cashmere label similar to the wool & mohair label pictured here. Â My guess, FWIW, is that this suit was sold at G&H in London.
