Your father's plug looks to be an old wooden atom. Most were unweighted, but Bob Pond did make a version with a long slug of lead along the tail wire (I think it was 2 3/4 x 1/4 but if you want to know for sure pm me and I'll dig out the xray next week) and sometimes a straighter taper to the tail. It looks like your father was reduplicating that idea.
