Old "real" Record iron bench vise was a bit sloppy and stiff. Bars were not staying true. Well, this version at the rear of the screw did not have a washer as an additional bearing on the back plate,* so over time, the pin wore and the plate was lose. Simple. A 16P nail is the right size. Bit of grease and good as new. ( cleaned the threads, lune, buff up etc.)
Sigh, even a vise needs maintenance.
* my one size up has a washer
