Exterior

• Bumpers:
  The bumpers are the same curved ones as on all Traction Avants until 1952 with the difference that the 7C doesn't have overriders (just like other pre war Traction Avants).

• Horns:
  The early 7C has it's horns on the front bumper as on the 7A and 7B. From November onwards the horns are mounted behind grilles in the wings. First these are secured to the back of the horn grille with a rubber ring in between. Due to the extra strain this puts on the wings this is later replaced by fitting the horns on a bracket on the bumper supports. These horns are still located behind the grilles in the wings.

• Grille:
  The grille is made from copper and chromed. All 1934 cars have the chevrons behind the grille. On some cars the bars and grille surround are seperate pieces.

• Front wings:
  The wings have a less high cut front point and look very small but are larger then those found on the 7A.
  Width (measured along headlight support): 68 cm
  Height (measured from headlight support straight down): 29,5 cm
  In November these wings are replaced by ones with small round grilles behind which the horns are mounted. The grilles are painted the same color as the wings but chromed or enamelled grilles are an option.Width and height of the wing are still the same.

• Headlights:
  The headlights are 200mm in diameter headlights and have flat glass. The headlight supports are completely closed.

• Bonnet:
  On the 7C the front shutters open at the front, on early cars all the shutter handles are still on the rear of the shutters, on later cars the front shutter handles are on the front.

• Windscreen surround:
  All 1934 cars have a chromed steel windscreen surround. Later cars have an aluminium surround.

• Wheels:
  All 7s have 5 stud wheels allround. Hubcaps are secured without the center bolt. The hubcap is pressed into a ring on the wheel. Tyre size is 140x40.

• Body:
  The 7C starts with the moleskin roof but from November onwards (serial number 51 000) this is replaced by a full steel roof. Other features are twin air inlets below the windscreen, no bootlid, flat floor without reinforcement dents and no raingutters as on the 7A and 7B. On the Cabriolet, there is no dickey seat lid handle. The dickey is opened by a lever on the hood tray.

• Doors:
  The doors don't have the alu trim strip and the rubber knobs are mounted in the doors, while on later cars these rubbers are mounted in the body.

• Rear wings:
  The rear wings are the same as those on the 7B. Each wing has a hole with a curved edge for a rear light 29 cm above the bottom of the wing..

• Rear lights:
  Two round rear lights are located in the rear wings. The lights have a pressed steel profiled edge and flat red glass with a small "lump" in the center.

• License plate holder:
  The illuminated license plate holder is mounted in the middle above the rear bumper, mounted on brackets secured between the body and the dress panel between the wings. The license plate is lit by painting the digit negatives on transparent plastic, with two lights behind the plastic in the holder.

• Spare wheel cover:
  The spare wheel cover is made up by several pieces. One piece is put on the body, after which the wheel is placed on the body and secured. Then the outer piece is put on the wheel. A chromed steel ring with a spring in it keeps the 2 pieces together. The hubcap is put on last securing the cover to the wheel.

Interior

• Floor:
  The floor is flat without reinforcement dents.

• Dashboard:
  The dashboard has a central placed combined speedometer (130 kmh) with white digits on black background. The oil pressure meter, fuel gauge (45 liter), amp meter and clock have black digits on white background and white meter hands. It also has 2 glove compartments. The lights are operated by a switch to the right of the speedometer and a ring on the steering wheel. The horns are operated by a knob in the centre of the steering wheel. The gear selector surround has arabic digits and is the same shape and size as the light switch surround. The gearlever has the same shape as on all later Traction Avants.

• Front seats:
  The early 7C has front seats with bars covering the seat. Later cars have plain cloth covers with small "buttons" and a chromed bar on top of the backrest.

• Rear seat:
  The rear bench is upholstered the same way as the front one. Because these cars don't have a boot lid, the rear back rest can be opened, hinging at the top and secured with 2 leather straps.

• Door panels:
  The door panels are from the same material as the benches and early cars have a curve stitched into them, filled with wood. Later cars have plain cloth door panels. The front doors have a small pocket for roadmaps.
