aeolian- graduola needles, reproducer arm+screws

Have a working condition Aeolian-vocalion Graduola, am looking for the following items:

locking screws for the reproducer arm. These screws must be VERY tiny-size similar to eye glass screws.
aeolian-vocalion reproducer arm. I have one, but is broken, previous owner glued it together...but am looking for a compatible replacement.
needles for the reproducer arm...
