Hi Patricia, I don't have any photos of the old Leas School but have you tried contacting the Wirral Archives on their website
www.wirral.gov.uk as they may be able to help you.
Just as a matter of interest are you in anyway related to the late Jim and Doris Moss of Moreton, and their son Peter and daughter Susan? My mother and her siblings went to Hoylake Parade School, and they had known Doris and Jim for most of their lives. As I was growing up we lived in the same road as Doris and Jim. Peter and Susan would be in their 70's now if they are still living.
