The mystery of a P107
From our friend Pascal Honegger we've got this question about a picture published in Citropassion n į 1 (April 2003) in an article about Pierre Terrasson, a man som works for CitroŽn in Montlhery at the testing laboratory in the thirties.

Look carefully at the picture: The car looks clear as a Kegresse P107, but the arrangement behind the driving wheel has two large wheels, connected by a large triangular plate!

According to Pascal, who made a overview on Kegresse with two large wheels, is this arrangement not know.
