Colour
White

Chassis 80926 is a very late Pre-A Porsche 356 1600 Speedster, one of only a small number delivered new in Belgium, and notable for carrying what appears to be the fourth-ever Type 616/1 1,571cc engine — an exceptionally rare specification for a Pre-A car. Sold new in November 1955 by D'Ieteren Frères in Brussels, it passed through Belgian and German ownership over several decades before a two-year concours-standard restoration was completed in 2014. The car retains matching numbers and original colour, and has demonstrated at multiple concours events since its restoration.

Maintenance & restoration

  1. 2012Restoration
    Acid-bath stripping by Lokeren-based specialist; final paintwork by Carosserie Symons, Borsbeek

    Full two-year concours-standard rebuild initiated after the car was repatriated to Belgium. Body stripped to bare metal via acid-bath immersion, all rusted or damaged sheet metal replaced (floor, battery box base, sills), and outer panels retained where sound. Individual body components are stamped with the last three digits of the chassis number, confirming matching panels.

    Assembly was carried out by the owner himself. New-old-stock parts used where originals were beyond saving; many original components including switchgear, lights, wheels and wiper blades were retained.

  2. 2012Engine rebuild
    Solex carburettors serviced by an unnamed specialist; electrical components overhauled by a Bosch service centre

    Complete overhaul of the original Type 616/1 engine (P 60 004) and gearbox: all crankshaft bearings, connecting rods, piston rings, valve guides and seats, seals, and gearbox bearings replaced. Solex 32 PBIC carburettors ultrasonically cleaned and refitted with new seals and jets. Engine and suspension components powder-coated or re-plated.

    The original engine had been removed at some point and a Super 90 unit fitted; the correct engine was reacquired with the car and fully rebuilt as part of the restoration.

  3. 2012Maintenance
    Bosch service centre

    Complete new wiring loom installed throughout the car; all electrical units including starter motor and alternator professionally overhauled.
