Oh man... here I am trying to sell off most of my collection, then I see a random craigslist ad where someone was trying to sell off most all of their really extensive collection for pretty cheap....
I picked up 9 horses from them, Breyers and Stones. $250 for all 9 of them, plus some Gen1 Stablemates. All in boxes. All fairly old, she stopped getting new ones 10 years ago. I got:
Seattle Slew
Lonesome Glory
Strapless (my childhood grail... finally)
The original Secretariat (the one with the rose garland)
Lone Ranger's Silver
AQHA Go Man Go
And three REALLY pretty ISH mold Peter Stones.
The haul:

The ISH Stones (they do have their original boxes, just cant see them from there):

(pics do not do these guys justice. they have some reeeally nice shading if you look at them in hand individually)
I'm like... exhausted from this. She had probably over 200 models. She had wood grains. She had glossy charcoals. She had original bulls, chalkies, pearlies, you name it, she had it, probably with the original box. She had Stones signed by Peter Stone! I'll probably ask her again later how much she still has left and see if I can pick up a few more for really cheap. She is quite the collector. I was really impressed. We talked Breyers for like, an hour. She didn't even say she had Stones in the ad! Just showed me the room she had all her horses in (and she said she had more that were in storage and weren't even out!), and there were a bunch of Stone boxes. Honestly I practically fainted.
