Double Sheave Block Appraisal

Antique Double-Sheave Wooden Block with Iron Hook

This is an antique double-sheave pulley block, commonly utilized in maritime or industrial hoisting during the late 19th to early 20th century. The block features an oval-shaped housing (shell) constructed from a dense, robust hardwood, likely ash or elm, designed to withstand significant tension. It contains two rotating internal wheels, known as sheaves, which appear to be made of cast iron or steel. The assembly is held together by internal metal straps and pins. Attached to the head of the block is a heavy-duty forged iron hook connected via a swivel eye, allowing for 360-degree rotation during use. Physically, the wood exhibits a rich, dark natural patina with visible grain and numerous signs of age and utility. Notable condition issues include deep surface cracks (checking), significant splintering at the edges of the wooden cheeks, and a weathered texture indicating exposure to elements. The iron components show a layer of dark oxidation and pitting consistent with antique metalware. There are no visible maker's marks in this view, though such blocks were standard equipment on sailing vessels and in barns. The craftsmanship is utilitarian and rugged, emphasizing functional durability over aesthetic finish.
