Sorry I wasn’t clear in my statement. I meant I only see rock dragons in test paints and not in regular production. Thanks for the reply though.
The rock dragons are not in regular production and have not been for quite a while. They were produced in cement for outdoor use when the Windstone factory was located in California. Since the factory moved to Oregon (five ? years ago), they don’t have the ability to cast in cement.
However, I noticed that the test paint large rock dragon recently on ebay was a gypsum piece like regular Windstones. So maybe they will start making rock dragons again some day and sell them for indoor use only. (Most people kept their rock dragons indoors anyway.) The test paint Little Rock dragons sold in the last few years are gypsum pieces but, again, nothing has been produced for regular sale.
Hope this helps!
