Paco, as well as Malone, have been at the forefront of the "casting" movement on Playclicks. So , yes, I am fairly certain it is as Richard has said, and these are castings from molds made from the original fence, and not repainted fences. In fact, I think those guys use tints in order to make their castings in color, and do not need any paint.
The Mofreaky duo have also been casting parts for quite a while, and I believe they even have a short demonstration "how to" video on their site.
