Blank verso showing offset of the recto drawings
Revealed as empty after restoration; only a faint mirror of the recto's machines bleeds through the paper.
The transcription records this side as having been invisible before restoration and as bearing no writing or drawings of its own. What appears on it is only the faint offset of the recto's pen work showing through the sheet, chiefly the tall runged frame and wheeled engine seen in reverse. No original text or figure belongs to this side.
