I have a Stag fiber optic light. It reads "Stag BEER". When plugged in, the letters twinkle in an alternating red and white repeating pattern. It's shadow-box style. The fiber optic tubes can be seen behind the letters, leading down to the bottom. The bottom, front right reads 5312 PB c. 1973 Carling Brewing Co., Belleville, ILL. A sticker on the back. top right reads "Manufactured Exclusively for STAG Carling Brewing Company, Belleville, Illinois by UMC Electropics, INC. Pat. NO. 3,184,872, Model NO. 5312 PS, Part NO. 108. What's it worth? Thanks for your help.
