Offering this nice clean, vintage 12 ounce, 5.25" long brass plumb bob, marked "B.K. ELLIOTT CLEVELAND PITTSBURGH" on the neck area.  The end cap is removeable and had good threads and a good snug fit.  The steel tip is also threaded and is removeable.  It looks like some storage dings in some areas, but otherwise little wear noted.   the point is pretty sharp, as shown in the pictures.. A nice clean example of a product sold by a distributor in Cleveland!  I believe B.K. ELLIOTT was a tool distributor not a manufacturer.
