I just picked up some old copies of Racing Illustrated, a European publication from the late 1800s. I've got a few spare minutes, so thought I'd send a few names that might be new for you....
Where I just say "white leg," that's generally something larger than your average sock but shorter than a stocking. And I hope the names are all correct. Some of the type was a bit faded/hard to read.
Immigrant - ch. h. 1890, by Exile II - Avonwick, by She Saw
Seems to have a blaze, nice long-legged model, three white legs. It appears all three are full stockings, with ragged edges at the tops
Whiston - ch. c. 1890, by Prism - Wild Mint, by Wild Oats
Nice blaze and one hind stocking
Rockdove - brown or black (?) filly, by Gallinule - Sleeping Beauty, by Ben Battle
Blaze face and three white legs
Marco - ch. c. by Barcaldine - Novitiate, by Hermit
Looks like he has a blaze, two hind stockings
Arcano - ch. (1891) by Mask - Annette
Large blaze, small white spots on ribcage that might be scars or photo problem
Ortolo - b. c. by Bend Or - Napoli, by Macaroni
Blaze, three white legs
Solaro - b.c. by Galopin - Capri
Blaze, two white legs
Crotanstown - ch. 1892, Gallinule or Favo- Lady Louisa, by Solon
Large blaze, three white legs (can't tell how high due to bandages)
Esther Clark - gorgeous! "black filly" - 1893, by Esterling - Rose Clark, by Speculum or Napsbury.
Right hind stocking, wide blaze.
When I find time I'll post more names, but perhaps one or two of these shall be new for you.
