The surviving parts of Layton’s collection can be found in several locations. The books, manuscripts, maps and prints are kept with the Local Studies Collection at Hounslow Library. Apart from the sword which Layton gave to the British Museum, most of the objects are at the Museum of London, though a few are at Gunnersbury Park Museum. Layton also presented fossil bones from the Kew Bridge Railway cutting to the British Museum and these form part of the research collections at the Natural History Museum.
