Not trying to be argumentative, but I'm pretty sure it's satin black, not gloss black. You can buy spray rust oleum with the primer included, this works really well for small areas like you have if you end up taking it down to the bare wood

I'm surprised no one else has commented. But I have done full cabinet restorations and small touch ups on B/W cabinets and I have always used satin black. To me it blends quite well. I would not brush paint with a regular brush, you will definitely see the strokes with black paint. For most areas I spray and just hold a piece of cardboard over the area(s) I need to protect. Cover the Playfield glass with something so paint will not settle on it from the air.
For really small areas you can spray one of those small foam brushes and use that to apply the paint and it will blend well.

I just did touch up on the front of a TOM that I picked up a few weeks ago, used the small foam brush with a little of the rustoleum satin black sprayed on the brush. You cannot see the freshly painted area.
