My goodness, so it is. I've been trying to ID the pictures below for some time.
The book has this to say:
Amphibious Car, Texier de la Caillerie
In June 1933 the French mechanised cavalry put out a requirement for an amphibious car. The only prototype offered by the French car industry came from a M. Texier de la Caillerie who had his design built by the firm of La Licarne. The vehicle was extremely novel in shape and had a punt-shaped chassis of duralumin with two large wheels each side. These provided the drive both on land and water and had scallop-shaped metal scoops attached to the wheel hubs to act as paddles in the water as the wheels revolved. Small wheels, one at the rear and two at the front, gave support while the vehicle was on land though these were free-running. Steering was effected by braking one of the big wheels as required, which was was simple in water but made road control extremely difficult. The engine was a 6 h.p. four-cylinder unit and on land there were three forward speeds and reverse. Normal top speed was 34 km.p.h. though 60 km.p.h. could be reached, but only with excessive fuel consumption. The vehicle carried a driver and passenger only. Trials were carried out in August 1935 in the Marne and a speed of 7 km.p.h. was obtained with the current and 5 km.p.h. in still water. While the design was not impractical it proved of limited military value in the eyes of the cavalry and they abandoned interest in it in favour of a design for an amphibios light tank. This latter also proved impractical but that is beyond the scope of this present volume.
