This is a set sold in Sweden in 1955 or 1956. The country of sale is shown by the "System i lek" ("leg" in Danish) and by the leaflet (yes, I can read Swedish and so I'm not just guessing).

I'm not sure the contents are original but all the 22 round bricks are of the (correct) vs02 in the types, colours and partial quantities depicted above. It must be noted that, if the 180º bricks counted twice, the complement would total 30 bricks.
