Bob - sorry to see this. You are correct - the 3d model was simply back cast. As the model had no work done to it, you now get the pleasure. I'm assuming this is also a slush-cast? That also adds some work if you want to thin it or cut out the windows.
As for the pin holes - those are most likely fissures due to the silicone rubber used for the mold not having all the air vacuumed out of it before pouring it over the master. The sad part is that makes the mold wear out even faster as resin gets in those and starts destroying the mold almost immediately.
Hope you're able to get it to work for you.
