|The Datsun 113 was in production from June 1956 through until September
Visually there is little to distinguish the Datsun 123 from
the previous 122 model. Externally the only change is to the front indicators.
The 122 had tall oval shaped indicators either side of the grille, on the
123 these have been replaced with very small round ones.
The only other difference between the 122 and the new 123
is the gearbox, but this represented a major change for the vehicle.
The 122 used a 4 speed floor change gearbox that was a copy
of the unit used in the Austin A40 Somerset, which Nissan was building
under licence at the time. For the 123 Nissan introduced their own gearbox,
which was a column change 4 speed gearbox with synchromesh on 2nd, 3rd
and 4th speeds.
The new Nissan designed gearbox was also 10kg lighter than the
old Austin box.
The column shift was seen as a major benefit in the Asian markets,
as it would allow for three people to be seated in the front bench seat,
but three full-sized European/American bodies would never be able to be
comfortably accomodated across a narrow Datsun.
The dashboard stayed essentially the same as the previous model,
with only a slight alteration to accomodate the shaft of the column change
that ran parallel to the steering column. The body featured a new floor,
with a much lower transmission tunnel. It continued to use the 860cc D-10
side valve engine. All other mechanicals were identical to the previous
The grille on the 123 remained the same as the one used on
the 122, with 4 wide horizontal bars and a wide chrome vertical bar in
