Here is a downloadable scan of an official French Navy drawing of the 120-gun ship-of-the-line Le Montebello, 1812-1889.  The drawing includes the starboard outboard profile and hull body plan.
 
Montebello was an Océan-class 120-gun ship of the line of the French Navy.  She took part in the Crimean war, the Siege of Sevastopol, the expedition to Kerch and in the Battle of Kinburn.  In 1860, Montebello replaced Suffren at Toulon as a school-ship for gunnery, and in 1867, she was used as a floating barracks.  She was scrapped in 1889. - from Wikipedia
 
The original scan was obtained from the discontinued website of the Service historique de la Defense but preserved by the Internet Archive "Wayback Machine".
