Help to open unknown chest

[goldpro]

Hi all, just wondering if anyone can identify the make of this box.
We need to open it and fit a key.
If you know what make it is can you provide a drill point or info
on how to pick it open, # of levers, etc?
The cover that slides over the keyhole is missing...only
the fixed part of it is still there...shown unscrewed from it's location.
There's a bit of gold paint coming through the brown on the door
but no other indication of a makers name or symbol.
I've included a few pics showing the few unique features of it.
the dimensions are 28" going parallel with the hinges and 22" both others
ways.

Thanks for any help you may provide.

Tom
