We have a Pulley with a screw top antique item.  It measures about 7" in L from the top of the screw to the bottom of the wheel x about 1 5/8" at the deepest point on the pulley top support with the wheel 3 3/4" across the center x about 3/4" in d on just the wheel.  The pulley wheel outer edges have some small chips of steel missing as I tried to show in my photo's.  The screw top is about 1 1/2" in l with some surface rust.  It has a nice look to it, in good condition.
