It is 5 inches tall, and 9 inches from where it is attached to the bottom stand, this is the measurement from under neath to the other side underneath. Diamiter is hard to do, because of the stand part, but its 3 /12 to 4 inches. The bottom is completely finished and polished does look as though it was meant to be part of the PW. The stand part is somewhat smaller than the gearshift knob I think it measures 1 1/2 inches tall. from the bottom to where its attached to the PW, it really looks as thought its all piece.
