I want to know the answer to the following question:
To the end of which era could you find 16 rpm setting on record players?
All the background I'm provided with is that "Subsequently, the 16 2⁄3 rpm speed was used for narrated publications for the blind and visually impaired, and were never widely commercially available, although it was common to see new turntable models with a 16 rpm speed setting produced as late as the 1970s.". Is that enough to answer the question?
Answer: yes
