Identifying this older vehicle

Original chassis numbers from before the modern VIN standard can be shorter and use manufacturer-specific formats. Do not add characters to make one fit a 17-character form. Compare the original markings with the registration papers and the correct period manual; a later registration or replacement identity plate needs its own supporting documents.

The NHTSA vPIC decoder is intended for model years 1981 onward. The specification rows below are a reference for comparison, not authentication of an individual car.

Specification reference from cardata.wiki. A question mark means a year boundary is missing from the source, not that production continues. An empty field means the source did not provide that value. Confirm the fitted engine, transmission and equipment against the car’s documents. How specification matching works.

Using the Mercedes-Benz Typ 540 K Cabriolet A (W29) specifications

Start with the car’s year, body and engine, then compare the matching row. Several variants may share a model name while differing in power, transmission or drive layout. If the advert conflicts with the registration or manufacturer documents, resolve the mismatch before relying on the specifications. The catalog does not authenticate an older vehicle’s chassis or restoration.
