Here's a challenge!

I've never seen one of these before.
This is a manufactured device used in a manufacturer's testing department.

This unit is made to plug in to 115V@60Hz and then it supplies the receptacles with 220V@50Hz. This is for the testing of all of the overseas appliances.

Here is the challenge......... Name the Countries associated with each receptacle shown. We'll number them from left to right, top to bottom.

Here is a clue......... There are 13 Countries involved.

This is just for fun! If I had to identify these........ no way!
