Retro ceiling light from 80's (Western Dearborn)

This light fixture was used in kitchen until recently when I updated. It holds 3 bulbs. Screws included. It works, but it might be good to replace wiring to be on the safe side since it is over 35 years old. It looks like it can be painted although you don't see the fixture much when hung. Glass dome is frosted with a line pattern on it. It will go in the trash if no one wants it.
