Very cool piggies! Where are the riders from?
Interesting, I would have expected questions about the pigs ...
Anyway, the riders are all Citadel, sculpted by Kev Adams, quite old and some very old. Most of them were slightly converted, getting new gobbo-faced shields, a new bow, and the left one was a standing orc with his hand sitting on his head. All had to be adjusted for fitting on the pigs, which came from the old Folio Works range Fantasy Warlord and had very nasty gobbo riders originally, but the piggies are really well sculpted. Unfortunately I don't know who sculpted them.
I had much fun putting them together, but fielding a rider force always means to paint 10 instead of 5 figures, that's the reason why we are not used to see much cavalry here ...
