45" overall length, 38" to middle hole. There are 5 original holes in good condition. An unusual brass buckle with the rectangular frame and integrated side loops is not a common Ralph Lauren design. It likely came from one of their short-run “Heritage Equestrian” collections or even early Double RL (RRL) pieces before RRL branding was standardized
The “Ralph Lauren – Made in England” mark was primarily used on high-end leather goods from the late 1980s through the mid-1990s, often crafted by British saddlery houses (like the same workshops that supplied Dunhill and Swaine Adeney). Those pieces typically featured solid brass hardware, hand-stitched bridle leather, and understated, equestrian-inspired buckles
Style: Equestrian bridle leather belt with solid brass bit-style buckle
