We have a lot of 5 kitchen tools vintage metal.  There is a ?doughnut maker which measures about 5 3/4" across from the handle to the outside of the round, 2 3/4" across the outer round and about 3/4" across the inner round.  It has tarnish and light rust, not recommended for actual use.  We have a slicer, round  with a few markings "Top Ring" 1, 2 , 3 and arrows on one side and the other with the numbers "707 - 2 - 3" in a rectangle on the other.  It measures about 4 1/2" across the center.  Lastly are 3 metal measuring cups 1 cup, 1/3 cup and 1/4 cup. The larger one has a few dents in it.
