This is an antique Sterling silver curling iron from the Victorian era, circa 1910. The item features a sterling silver handle with a steel top component used for curling hair. These elegant vanity pieces were commonly used in Victorian times and represent the craftsmanship of early 20th century beauty tools.

The curling iron typically measures approximately 7-3/8 inches in length with a 3/4 inch barrel. The handle is made of sterling silver (.925) with intricate Art Nouveau or decorative detailing, while the shaft and clamp portion are made of steel. Sterling silver handles were designed to be hollow or plaster-filled to prevent heat transmission from the hot curling barrel to the user's hand.

This complete set includes various styles, making it a valuable collectible piece for antique enthusiasts or historians interested in early beauty and grooming implements. The "U6" designation likely refers to a specific size or model variation within the Sterling line of curling irons.
