Was that a shellac disc, rather than vinyl? I could picture that dying with or without the depression due to low quality compared to 78s.

From Wikipedia https://en.wikipedia.org/wiki/LP_record

RCA Victor introduced an early version of a long-playing record for home use in September 1931. These "Program Transcription" discs, as Victor called them, played at ​33 1⁄3 rpm and used a somewhat finer and more closely spaced groove than typical 78s. They were to be played with a special "Chromium Orange" chrome-plated steel needle. The 10-inch discs, mostly used for popular and light classical music, were normally pressed in shellac, but the 12-inch discs, mostly used for "serious" classical music, were normally pressed in Victor's new vinyl-based Victrolac compound, which provided a much quieter playing surface. They could hold up to 15 minutes per side.

Had to look it up. I have a changer mech, but no records of that format. This is the same mech I have: https://www.youtube.com/watch?v=87P7xygDcs0
