Between the years 1926 and 1933 Enderlin (I) played a total of 138 games for Basel scoring 68 goals.
A well-documented curiosity was that at the end of Basel's 1929–30 season, the team set off on a Scandinavian football tour, including a visit to Germany.
The journey started with a train ride on 2 June 1930 at quarter past seven in the morning from Basel and they arrived in Leipzig at half passed eight that evening.
Finally, the tour ended with three train journeys in three days, Bergen/Oslo/Berlin/Basel, arriving at home on 20 June.
The result of this tour was seven games, four wins, one draw, two defeats and approximately 160 hours of travelling.
