This weekend's meeting between Scotland and Wales is the 114th cap match between the sides since 1883.
Wales lead by 62 wins to 48 and the matches of 1885 (at Glasgow), 1922 (at Inverleith in Edinburgh) and 2001 (at Murrayfield) were drawn. Wales have won five of the last six matches, including a World Cup warm-up game at Cardiff in 2003.
Although Scotland won by four goals and eight tries to nil in 1887, that result was before scoring by points was introduced. Their 35-10 result at Inverleith in 1924 is the biggest win and their highest score of the series.
Wales set the record for the highest score in their best win of the series at Murrayfield in the 2005 Grand Slam season. They won 46-22.
Neil Jenkins made the highest individual contribution to a match in the series, collecting 23 points at Murrayfield in 2001. Chris Paterson scored 21 (all penalties) for Scotland at Murrayfield in 2007.
The only player who has finished a match in this series with a full house of scoring actions to his name is Craig Chalmers. He scorred a try, conversion, penalty goal and dropped goal for Scotland at Murrayfield in 1991.
George Lindsay's five tries for Scotland in the 1887 match is a tally that still stands as the record for any game in the International Championship. Reggie Gibbs recorded the only try hat-trick for Wales, at Inverleith in 1911.
Chris Paterson heads the overall scorers in the matches. He has collected 91 points to date and has scored all of Scotland's points in their last two games against Wales. Stephen Jones is the leading overall scorer for Wales with 89 points, one more than Neil Jenkins scored against Scotland.
Billy Trew (in the early 1900s) and J P R Williams (from 1969 and 1981) each played in a dozen matches for Wales, the series record. The corresponding record for Scotland is shared between Jim Renwick and Scott Hastings, who each played eleven times.
If he plays, Chris Paterson will become the most capped Scotsman in the International Championship. At present he shares that distinction with
