I have tried my best but have failed. Asking for help identifying this font.
It is the font used for fingerings in very old books of sheet music. Here is an example from a book published in 1976:
I have looked all over, coming closest with Century font, but either the 4 is different, or the bottom of the 2 is different. I installed some music composition software, and the font it uses for fingerings is not even close. I am hoping someone can recognize this font.
