British RAF Queen's Crown Mess Waiter Button

Material: Chrome-plated metal, convex with integral shank
Size: 25mm
Description: The face of the button features a deeply struck relief depicting a soaring eagle with its wings outstretched horizontally, looking towards its left side. Positioned directly above the eagle is the St. Edward's Crown, historically recognized as the Queen's Crown, which serves as a definitive marker of British monarchy allegiance during the reign of Queen Elizabeth II. Measuring 25mm in diameter, the piece is entirely flat across its surface and lacks the typical raised border rim found on standard service dress components. The reverse side is completely smooth, entirely devoid of manufacturer stamps, and relies on a single integrated metal loop shank to attach securely to uniform fabrics.
Circa: 1953-2022
Notes:
 While frontline officers traditionally favored gilt brass or modern anodized aluminum ("Staybrite") insignia, these distinctively bright, flat chrome-plated variations were primarily produced for the service uniforms of RAF mess waiters, band musicians, and civilian support personnel.
