Hello,
Seems that Gaga has to do some more serious research on Algérie, as the cruiseur was equiped in mid-1942 with a Détecteur électro Magnétique (DEM) on top of the tower, an early radar set in a certain manner. Its four antennas were installed on yardarms at each corner of the tower and were more of a tubular square frame box than a circular dish.

Also please note that general appearance of the ship was different when compared to the early war years, with addition of some light AA guns.
Best regards from Normandie,
Jacques
