I have a fantastic Joseph R, Razor that i aquired, it is perfect, but the pin has a little bit of play, its like the pin hole in the blade its rusted a little bigger, its not real problem to shave with. So my father said just leave it and run some oil with an anti oxidation compound added into it once a year. But what do the pros think here? get it disassembled, drilled and re pinned or just leave it?? i must add its not the scales are loose there is slight play in one horizontal direction..
