Porsche 356 Pre-A: features and differences
Windscreen, bodywork and details of Porsche 356 Pre-A models: understanding the versions and planning checks before restoration.
Key points
- Pre-A identifies the family preceding the 356 A, not an identical specification for every year.
- Model year, production date and first registration must be distinguished.
- Exterior details help with orientation; identifying the car requires documents and checks.
A Porsche 356 Pre-A should be understood as a set of elements consistent with its production period. The windscreen is a useful clue, but it cannot alone date a car or determine the quality of its restoration. Body panels, lights, engine, trim and interiors may have changed over time.
What Pre-A means
The designation distinguishes early 356s from the later A series, introduced in September 1955. The 356/1 Roadster must also be distinguished from the 356/2 cars built in Gmünd and from subsequent cars: these are not interchangeable names for the same automobile. The Porsche Classic historical model pages distinguish these families; the 356 A page dates the transition to the new series.
Windscreen and bodywork details
Early coupés have a windscreen divided in two by a central pillar. Later Pre-As introduced a one-piece windscreen with a central bend; the A brought the curved panoramic windscreen. Bumpers, lights and the bonnet handle also changed during production. Open versions require specific comparisons: the windscreen rules used for a coupé should not automatically be applied to them.
These differences are described in the cited Porsche model pages. For an assessment, photograph details from the front and side, note the stated version and check inconsistent points one by one. An internet photograph may itself show a modified example: it is not a universal standard of originality.
Build a file before ordering parts
The initial collection should include legible identifiers, available production documents, photographs before work and a parts inventory. It helps to separate three columns: what is present, what is expected for that car and the reference used for comparison.
- Bodywork: panel configuration, openings, fit and visible repairs.
- Cabin: instruments, upholstery, controls and evidence of replacements.
- Mechanical components: types and numbers of the assemblies installed, before discussing whether they match the originals.
- Dismantled parts: photographs, quantities and position, avoiding discarding components simply because they are worn.
How to use this information in restoration
The project should state the specification being used as its reference and which decisions still need verification. If a detail is undocumented, the correct response is to reserve judgement. Buying a spare part immediately may make a later correction more expensive.

Frequently asked questions
Must a Pre-A always have a split windscreen?
No. Coupés in the Pre-A family also include later one-piece windscreens with a central bend. The specification must be checked against the period and body style.
Does the year on the registration document identify every correct part?
No. The car must be compared with relevant documentation, taking account of changes during production.
