For an original Haflinger vehicle which retains its original Steyr Daimler Puch identification plate, the vehicle is chassis number, engine number and build number can be obtained from this single source. Many Australian-delivered Haflingers had the manufacturing date un-stamped. This plate is found at the forward –left of the drivers seat, adjacent to the front left seat fixing bolt. SDP originally used a blind dome-headed rivet to fix the ID plate, and so if a plate is affixed with pop-rivets, it has been removed at some point. Many Haflingers in Australia are missing their original ID plates.
To verify that the ID plate is original and the details are correct, or to identify the vehicle if the ID plate is missing, the chassis number can be obtained from the side of the gearbox. This number can be seen on the drivers side of the gearbox. There is no guarantee if this is the original chassis number, as the gearbox may have been exchanged at some point over the last 40-50 years. However this chassis number is not stamped anywhere else on the vehicle.
The engine number can be readily seen on the engine block, below and to the left of the pully-wheel. Many surviving Haflingers in Australia have had their engines replaced at some point.
To determine the manufacture date, export date and to whom it was first sold (usually the importer), it is helpful to obtain a copy of the Wagenstammkarte or build certificate. This certificate can also be used to confirm the original chassis and engine numbers. A copy of the Wagenstammkarte can be obtained through Haflinger Technik in Scotland. This certificate also provides detail on specifications and options as it left the factory, for example type of sideboards or side rails (if any), rear seats, carburettor type, battery type etc.
Australian Army Haflingers were in addition fitted with two black&silver type plates, one of which was stamped with the chassis number. These plates were fitted forward of the front passenger seat.
