I ust bought a used N90s, serial #2007xxx. I have two questions, first- does anyone know at what number serial number they started marking the N90s with. Second, when I rewind the film, along with the usual mechanical noise associated with the rewinding there is also a sort of screech or whining noise, can anyone shed any light on whether this is usual for older N90s or is this indicative of a future problem?
