Looks like a special aluminum or steel plug made to seal off the fuel pump push rod area in a Flathead engine, by using the tension of valve guide retainer/crows foot, held in place by a hex head machine screw, and a hex head bolt through plug, and threaded into plug to block off hole for mechanical fuel pump push rod. The saftey wire feature is to help keep hex head bolt from backing out
