Toot-A-Loop Radio - 02

National Panasonic Toot-A-Loop or R72, model R72-S. Part-radio and part-fashion accessory, the 1970s Toot-A-Loop was an unusual wearable technology. Worn around the wrist like a bracelet or carried like a purse, it was shaped like a tapered doughnut, twisting open to reveal the tuning dial on the inside. One side of the radio has a grille for the speaker. There is also a jack for a mono earplug. The R72 has to be twisted into the "S" position in order to be tuned, but the volume control is on the outer side of the radio and can be adjusted regardless of whether the radio is twisted, open or closed. In working order, it requires 1 x 9v battery.
