Also where did the Lyttleton Ward come from, there doesn't to be any reference to this being a unit or part of the hospital in any other records?
however I managed to find that Lyttleton was the author of the manual of lunacy

http://studymore.org.uk/4_13_TA.HTM - shows all the history and no mention of Lyttleton at all
1948 Management transferred to the National Health Service. Netherne continued to serve the eastern half of Surrey and Brookwood the western. Hospital management came under the overall control of the South West Metropolitan Regional Hospital Board. the hospital came under the direct control of the Netherne Hospital Management Committee from 1948 to 1964.
1971 - Hospital under the direct control of Redhill and Netherne Group Hospital Management Committee - formed in 1964 on the amalgamation of the Netherne Hospital and the Redhill Group Hospital Management Committees. The latter body administered a number of institutions.
i found a copy of the lunacy manual (it feels horrible typing that) - https://wellcomecollection.org/works/bx3hzb5f/items?canvas=62&query=netherne
page 42 - details on a case book - an act passed by parliament that all admissions should be recoded including a description of appearance, I don't think they have been digitised though
which can be found here - https://discovery.nationalarchives.gov.uk/details/r/C10937
