I, myself, think that Hamilton made the original mass markings, but you can find other different sets of them scattered around.
If you have:
Merle, Merle with socks, Helm, Cape, Raccoon, Flag, High half, High tip, double tip, double ring high, double ring low, eye blaze, eye patch, eye stripe, ear spot, ear ring, ear stripes, ear tip, TLK (feline only), eye spot, cheek spots, fox (canine only), nose spot (canine only), pinstripe, back cross, leg cross, double cross, corgi (canine only), corgi2 (Canine only), tongue, mustache, bear, goatee, those brows, lat stripe, cross, half muzzle, shoulder blaze, side blaze, chest blaze, points, belt, half belt, foot, glove, pawpads, super stripes (feline only), orbs, starry, hexes, half dragon, (feline only), small kippot, bif kippot, freckles1, freckles2, top stripe, brindle (canine only), half spot (canine only), or smilodon.. then you have the original mass markings. I hope this answers your question. ^^;
