I saw a post recently about the above topic. If you go to https://discovery.nationalarchives.gov.uk/results/r?_q=ho129, there are 659 files to download. I scrolled through a couple of pages, and there are a number of local parishes, including West Derby.

You have to register with the site, but currently downloads are free, so fill your boots and start downloading!
