The Ronstan RF288 is used on many dinghies as a wire halyard jib block. The block is integral to the forestay and utilizes an upper and lower forestay. This used block comes with  a used upper forestay which is of 3/16" diameter wire. A thimble for the lower forestay is also included. Note that the lower forestay IS NOT included. This item shows some cosmetic staining from normal use, but appears to be in fully serviceable condition. What you see in the photos is the actual item you will receive. As used rigging I can not guarantee any load rating so use this at your own risk.
