Building a replacement case - questions

[ununiform]

I bought a 72 Fender Rhodes that was missing the case top. The bottom has a few spots where the wood is smashed in so I took a CNC class and am about ready to build a replacement case.

The bottom is going to be pretty easy since I have the bottom I can model it after, but I'm a bit stuck on the top and can't find good photos to see what I'm up against. The top has what looks like a compartment That I imagine could hold cables and such. Is this a hinged opening or is it held in place in a particular way?

Could anyone out there send me some pics or a short video that would show what this compartment is all about?

Also, Is the inner top covered in tolex or felt? or is it painted plywood?

On every stage piano I've ever seen the entire lid is tolex - inside and out. Sparkletop & piano bass lids were lined with felt, but I believe they were the exception.
