Thanks for your quick and incredibly detailed response.
I was hoping you would chime in here as I've spent a lot of time here recently, and come to respect your sage wisdom.
My 442 (clone - actually an '82) was meticulously built by my Brother over many years and the interior was totally redone, including the addition of the lightning rod shifters that came out of my Brother-in-law's totalled '84
Hurst Olds.
The wood grain pattern in mine looks like the 'swivel walnut' that you describe, yes? It's the same throughout the interior.

The only thing missing is the tray itself and probably the two rubber buttons on each side.
My research led me to the following site which shows just the metal tray (stamping):
1984 Oldsmobile Cutlass/442/F85 CONSOLE ASHTRAY GM 22528634 – EA

There's one on fleebay too for $30.
I don't mind ordering this thing if I have to, but thought I would reach out for options - anyone else?
Thanks again.
