Brushed

I took the wire brush to a couple of the shapes. On the nearest you can see where the hole in the sand allowed just a nubbin of copper to rise up once the foam void had been filled. I have cut off the bulk of the pouring sprue in the front two, but left a piece at the back of each, originally to allow me to grip the pieces in a vice while chasing etc, but eventually left on, drilled and threaded to act as a mounting stub. I realized too late that I had sprued up the back one facing the wrong way, so I cut that one off flush and welded on a similar stub instead on the other side.
