Old mathematics fonts, names and availability?

[a2009]

This isn't exactly a physics question, but oh well.


I was recently looking through some old physics papers (from 50s and 60s) and really enjoyed the way their equations looked.

Does anyone know if these Greek and mathematical symobl fonts are available?
What are they called?


Thanks

Would you mind posting some examples so that we may have some sort of reference to go by?

The math is really clean.
