Criterion 20 1/2 Music Box Disc…“Triumphal March, From Aida”. Included is a nice condition 20 1/2 inch Criterion Music Box Disc. The disc appears to be in good condition with no teeth missing on the disc that I can see. The disc number is: 5209. Criterion & Olympia discs both have the same size center hole (3/8″). These disc are interchangeable. We are using a stock photo for all the disc that we have. They are all similar in looks and condition. Anything different, we will mention here. Any questions, feel free to ask!
