I've been having a bit of a sort out and came across these brass castings. They are 1and 3/8 inches across and the boss in the centre has a 3/16 hole right through with a cross hole for what I would imagine would be a fixing pin. The small rounded piece has cross hatching on so looks like some sort of tap with a pointer. The top three have had bits filed away.
Has anyone seen these before?
