Skylight brackets

I collected these frames from the sheetmetal shop today. They had done a very good job, quick and at a good price. I’d had 4 made up - 2 of each orientation, and I riveted the opposites together. This replaces the original ones that were a work-around from the center stringers. It provides a flange that the wing fairing strips can rest on, and if necessary, be screwed to.
