This ring is accepted in the hobby as a Buck Rogers item c. 1953 as it was issued at the time when Sylvania television was a Buck Rogers licensee and they used Buck extensively to promote their Sylvania halo light televisions. The ring has a large brass base with adjustable bands and the company “S” logo on each side. Top of the ring has a pair of lightning bolts surrounding high relief white plastic light bulb replica which glows brightly in the dark. The surface of the bulb is marked with their full name and “S” logo and the black color detailing this text is 85% complete rather than typically being almost totally worn off. Nice luster over the brass ring base. Exc.
