Not sure anyone has said anything that is a reservation about its age? Just a discussion around age of stops in general?Not sure the reservations people seem to have, if I needed a Stop I'd snap that up right away. They don't make them like they used to!
As long as the main bobbin nut is tight good and solid, it should be fine, better than a new one. I'd use it!!
