The larger (and more scarce) of the two Hg-filled plumb bobs offered by Starrett, this example is clean and shiny, with only one small spot of corrosion in the nickel plating. This one is the second from the largest size, being 5 1/2” long, 7/8” diameter, and weighing 12 oz. It is one of the best plumb bobs. Fine.
