It is just a simple SunTour protector on my wife's lowly Bridgestone, not beautiful in itself. But that it is there after nearly 4 decades is what I like. I think the only bike I have other than my Domane without one is my Raleigh. The Raleigh would have had a plastic one and in '84 it would have been appropriate to tear it off anyway I suppose. In fact I probably would have taken them off almost anything back then if it was what the cool kids were doing.
Also I agree with the posts above to get the proper FW tool anyway. The tool is cheap enough and if the OP is going to do work and maintenance on old bikes it is pretty much a necessary item to have on hand. Then they can clean and service the FW before cleaning up their spoke protector and putting it back on.
