Classic Uruguayan socket and plug with angled power pins (IRAM 2071, 2073). The text on the socket - 10 AMP. 250 V. - and the orientation of outlets of adapter no. 13 suggest that the device has to be mounted in a 180 degrees rotated position (as comparable U.S. sockets). However, it seems that nowadays in Argentina and Uruguay sockets are preferably mounted in the shown orientation. The 'C' logo may refer to an unknown manufacturer.   {PS}
