No, it hasnt been mentioned.

I found the folks who actually made the tomb, and cut down the list of 'interesting' elements, by mentioning to Ez' and OP, what items were stock parts.

The dimensions of the tomb and specific placement of the window, and of course the actual window design, are relevant, as are the gluphs on the glass part of the door.

These were specifically requested.

They would not expand on the design at all.
