Help with Sonora

[NewGuy]

Hello,

I just purchasing my first victrola, a Sonora. It plays great! I'd love to restore it. I can't seem to locate the model #. Not under the cover nor on the back. There is a backboard but it doesn't seem to come off.
Can someone help with this and any tips to restore the wood? Some of the veneer is off and coming off.

Thanks for anything, Jay
