Vintage Pilot's Leather Flight Helmet with Integrated Headset

This item is a vintage pilot's leather flight helmet, likely dating from the mid-20th century, possibly World War II era or slightly later. The helmet is constructed primarily from dark brown or black weathered leather, showing significant signs of age and use. The exterior leather is wrinkled and scuffed in various places, indicating a rich patina acquired over decades. The interior appears to be lined with a lighter, possibly tan or beige, fabric or soft leather material. Integrated into the helmet is a wired headset system. Earphone cavities are evident on both sides, featuring metal grommets and possibly containing internal components (not visible). A prominent feature is the microphone boom, which consists of a rigid, curved, light-brown colored tube, possibly plastic or hard rubber, attached to the side of the helmet. The boom's attachment point is secured with dark brown leather straps and metal fasteners. A fabric-covered electrical cord, also light brown or olive drab, extends from the helmet, intricately woven and secured to various points with small leather loops and stitching. This cord leads to a large, black, multi-pronged audio jack, which appears to be of an earlier standard, possibly a 1/4 inch or similar gauge, designed for historical radio or intercommunication systems. Near the jack, a spring-like strain relief is visible on the cord, and a small, light-colored fabric-wrapped component (possibly a switch or small junction box) is also attached to the cord further up. The overall craftsmanship suggests a utilitarian military or aviation-grade item, built for durability and function rather than aesthetics. There's visible fraying on some of the fabric elements and general wear consistent with its age and intended use in harsh environments. The metal components show some oxidation. No discernible maker's marks or specific model numbers are visible in the provided images.
