Hi Vals**********, There is a booklet on Wythenshawe, don't know by who but, it shows lots of pics prior to the land becoming the Wythenshawe estate, old maps in there too, I'm sure you will find the info if you ring Wythenshawe Library or Manchester central library.
In the science museum on Liverpool street in Manchester, they have films in there to watch, The Garden City, as it came about, not sure if you can get copies, you have to ask.
regards,
