Rare Vintage Rally Accessory

On http://forums.pre67vw.com/ I came across these pictures of a nice Zwitter. The owner has added some really nice accessories to it, especially the  front hood. Ever seen three head lights on a bug? No? Just take a look at this picture. A very nice accessory, don’t you think? When was the last time you saw a front hood like that? This rare Volkswagen accessory could be found on rally bugs in the early fifties. This Zwitter was seen on a local VW event in Bad Rappenau, Germany. The owner is also working on a pre A Porsche 356 engine for it. Talking about a real vintage race monster! It certainly left me with some questions… Who made this accessory and is this the only car known fitted with a rally front hood or do more examples exist today?
