Sam,

If I remember right, out machine was a Noritusu 1290? Could be a 1400 series, it has been a few years since I worked there! on the right hand side of the machine there was a dial that would allow us to vary processing times, to allow up to a 2 stop push or pull, we also had a keypad on the right hand side that was used to check process temps and such, but both our C41 and our E6 machine had this feature to allow us to vary processing times.
