Neither do I and unfortunately Tim has not attributed it in any way.
He is not doing himself any favours with his site. Having read this item I then tried to find it on the site and couldn’t. It’s called The Ghost of Uncle Ab but is not listed in the index. Neither is it listed under the Ghosts & Ghouls section. I then tried the recent pages page in case it was new but it is not listed there although he does claim to have added 45 pages in 2014!!!! Eventually I found it in the main index under Ab’s Ghost.
As I commented before, the content of the site is excellent but it’s organisation, indexing and search facilities are not. Once a site gets this big it does need to be well organised and each pages should be dated to show when it was written and last updated.
