A Normandie Nursing Bottle is listed (N22) in A Guide to American Nursing Bottles by Diane Ostrander, 1992, published by the American Collectors of Infant Feeders. This type was made by Barclay Mfg. Co, and avertised in the 1887 to 1909 Whitall-Tatum catalogues. Hope this is useful. Alan Humphries, Thackray Medical Museum, Leeds, UK. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
