You are buying a vintage Northwood yellow opalescent vaseline glass pump and trough. There is just one small tiny pinhole imperfection on the rim of the trough as pictured.  It is not a chip or fleabite, but you can feel it.  I am not an expert as to the proper term to give it but I did want to note it.  Also there is one scratch on the bottom of the trough as pictured. Considering the age of these pieces, they are in still in great shape.  The trough is 5 inches x 2 1/2 inches and stands 2 inches high.  The pump stands just over 6 1/2 inches tall.  It is about 4 1/4 inches wide from the tip of the handle to the tip of the little pump.  Both pieces have these bumps or nodules on the outside of the glass which gives it such an interesting look.  Also, on the rim of the pump around the top, there looks like there are sunbeams in the white opalescent part.  It is very noticeable in the light and looks beautiful.  Enjoy.
