 The tuner was located inside one of the "splits," so the radio had to be twisted into the "S" position in order to be tuned, but the volume control was on the outer diameter of the radio and could be adjusted regardless of whether the radio was twisted open or closed.The Toot-a-Loop came in several colors including white, red, blue, and yellow.It was also produced in two other colors orange and lime which were sold in Australia and New Zealand.
