I would like to find a Titanic picture showing the same kind of lamp it still exists today on board the Nomadic. Mr Vanhoutte, webmaster of the website www.nomadic.st.fr, said they are the sameones than in the "2d class reading great saloon" or perhaps "2d class reading room".
If it looks you uncorrect, could you have a look at the Nomadic website ? Sorry, it's in french ! Choose "Photos" (at left), then "Mai 2000 - A la recherche du passé ..." (at the top right corner)and you will find the picture of a white lamp.
For what it's worth, there was a 2nd Class Library on C deck just inside the 2nd Class Promenade. What makes this confusing, I believe, is there is no 1st Class Library - it is called the 1st Class "Reading and Writing Room" and is located foredeck A.
