A few weeks ago, Breyer Horse Diva wrote a blog entry about an unusual Western Horse she had found at a flea market. The model whose picture she posted (below) looked familiar - I have a palomino Western Horse that I'd found at Gordyville years ago with the same unusual black hooves.
Breyer History Diva's horse above, and mine below.
Mine is definitely an older piece - you can tell by the color and the saddle, plus it has the older style chain reins. You can see its black hooves which are so like her model's.
Sadly, you can also see that my model has begin to deteriorate. Notice how the hind hooves are beginning to curve under? That's happened since I bought the piece - I would not buy a model in such poor condition.
The hind legs are discoloring as the plastic disintegrates.
And there are flecks of odd bits and colorings in the white socks. Notice how the black hooves are fading in color, too.
It is well documented within the hobby that sometimes Breyers deteriorate over time. Some bloat ("bloaties") especially if they are exposed to heat. "Shrinkies" begin to shrink with time, and usually are models which were produced during the 1970s oil crisis when Breyer used different formulations for its plastics. (I have a shrinky; my dapple grey 5 Gaiter is significantly smaller than its counterparts.)
"Oozies" actually liquify and leak. At that point, most hobbyists remove the model from display so it won't mar the finish of the shelf or harm the nearby models. I've been told that often oozies are accompanied by a vinegary smell, often the first indicator that the model will begin leaking. And some collectors actually lick their models and say the vinegary smell indicates a vinegary taste on the piece! (Okay, I admit I licked my 5 Gaiter to see if it might be an oozie. But, that piece is not one I got at a flea market - I know its history - and I keep it very clean.)
I wonder if perhaps my Western Horse got too much sun upstairs in the horse room. It's on the bottom shelf, and it does get direct sunlight briefly sometimes. None of the other models are affected, at least not that I can see. I'll make a better effort to keep the blinds closed in the summer, but it is far too late for this piece.
