19th century sleeping cars

[D9007_Pinza]

G'day all, I am currently seeking information or photographs (especially interior) relating to sleeping carriages based on the designs of Gustav Leve and Adolphus Davis. Two of them were imported to the NSW Government Railways in 1883 by Gilbert, Bush & Co, however I have so far been unable to find any information about similar carriages built and operated in North America, or anywhere else. Locations of any survivors would be hugely appreciated too.

Leve patent:

I am also seeking leads to any other surviving sleeping cars built in the 1875-1890 period, if you can help this will be greatly helpful.
