Vintage Crosby Steel Block Tackle Hoist Pulley.
Item comes in very old, used condition. Does have some rust and debris in the crevices. Not sure if it is missing the piece that is attached to the hook portion for securing shackles. Both of the pulleys appear to move as intended. The item does have permanent marker written on it on both sides. Does still appear to be a pretty solid piece. Not sure what the weight capacity is. Has a number 5 engraved on the item, including the manufacturer which appears to be Crosby WB. Co. The size of the item is approximately 12 inches in height by 3.5 inches in width. The pulleys are about 2 inches in depth. Free shipping!
