The tournament was known as SKIM with a K, but I guess the engraver could have made a spelling error, or they could have tried to make it sound more international with a SC for Scandinavia.
I find it unlikely that there would have been two competitions in the small town of Jönköping the same year, one called SKIM and the other SCIM.
And SKIM was won by an American, which would also explain how it ended up there.
