We have 6 hooks which 5 of them are brass and 1 metal.  They are all about the same size give or take a bit with the 3 that match being about 1 1/4 from the round to the bottom/top of the hook with the screw extending another 1/2", the same hook is about 7/8" across the center of the round.  They have all been used - they are in gently worn nice condition.
