I have always assumed the horses are Clydesdales, but I really don't know for sure.
I'd love to hear from someone who can do a positive identification.
Continuing the theme of Clydesdale Horses here is the song "Heavy Horses" written by Ian Anderson and performed by Jethro Tull
Heavy Horses, move the land under me
Behind the plough gliding --- slipping and sliding free
Now you're down to the few
And there's no work to do
The tractor's on its way.
The band Jethro Tull took their name from the 18th century agriculturist who invented the *horse* drawn seed drill.
To bring all the connections full-circle, Ian Anderson of the band, who wrote the song Heavy Horses, used to live on Skye, where the photograph was taken.
