Sounds like a difficult assignment to find one for sale.
On my model, that door is very simple, although I would have trouble producing the panels and getting it to match the rest of the mahogany.
It's held on by a full length piano hinge, and he latch is the simplest possible--a lever that falls into a catch.
I might consider having the piece cut from acrylic (lucite). You could pick a color to complement your custom interior (which I like).
Acrylic is a handsome, tough material that's easy to work with tools.
It would not need finishing or trim or any kind.
Just an idea....
