I don't have any Manchester printings of Skewball and I have seen all the sources so far mentioned. Harkness is the nearest geographically, but I'll check all my copies to see which other horses are mentioned. If you want to identify the race itself the 'Turf Register' would be a good place to start.

Here goes. These are immediately accessible copies.
