Hello,
Currently on ebay is a photo of a Gotha G.IV. The serial is difficult to see clearly but may be 238 making Gotha G.IV (SSW) G.238/17 a possibility.The photo is at:

Alternatively do any of the French users of this board (or indeed anyone else) have any knowledge of a Gotha G.IV exhibited at Nancy?
Regards,
Clint
