I’ve known of the puzzle VW ever since you posted it back in 2016, but frustratingly couldn’t find the German book it was featured in. I’ve now found that book, so can confirm that this is a bodykit for the Type 1 (Kafer, Beetle, etc.) developed by a Herr Blum as a 270 DM upgrade to a standard Type 1 in the early 1970s, using VW 411 lights. More pictures to follow shortly
