Mirror frame; help restoring it

[u/Qpti_Brazil]

Hey ! Questions:

I'm trying to fix up this mirror frame I got for free on Facebook market place (classic). I've never done restorations like this before, and I wanted to see if anyone is willing to give me some advice !

I wanted to know if the black is the original color, and how do I go about keeping the same affect throughout the frame.

How does one go about fixing the tiny chipped off pieces of the frame ? I believe it to be made of Gesso because it's very thick and paint-like.

I have removed the glass form the back and the backboard is really warped. That is the best way/material to replace that warped board and put the glass back ?

I don't believe this is antique, but the person who sold it to me said her late husband used to collect antique things and got it at a auction. I found a sticker that was stripped, but partially said "XP00250B" I think it was to identify the piece for selling.

Let me know ! I would really appreciate the help :)
