I have a large hook with a swivel top marked Crosby Laughlin, Vintage Item.  The hook  measures about 5  3/4" in length x about 7/8" in depth x about 3" in W across the widest point of the hook.  The swivel is the full round 360 degree.  It is painted red with some missing finish but mostly in tact.  Upon initial listing I have a 2nd identical one available.
