I need a gearset for a TT-4/TG to operate at 404 OPM / 66WPM / 50 baud. I am happy to exchange a 368.1 OPM / 60 WPM / 45.45 baud set and a 600 OPM / 100 WPM set. The TT-4 manual states that the 368.1 OPM set is normally fitted and the 404 OPM set is held inside the machine. My machine is fitted with a 368.1 OPM set holds a 600 OPM set.

I am located in Adelaide Australia and am happy to pay parcel post both ways.
