No, they were two completely different teams. The colour of the Stichts Racing Team - S.R.T. - cars were white with the Dutch stripes on the front until '68 (TI Super with Hans Oskamp and Henk van Zalinge, GTA with Nico Chiotakis and Johnny Muller), B.F. Woltering ran the team. The cars were white in '70 (GTAJ with Wim Boshuis, already sponsored by Elf), red and later Giallo Ocra in '70 (GTAm with Hezemans sponsored by Elf, too), and that kind of dark turquoise in '71 (GTAm with Liane Engeman, later Jan van der Pol, GTAJ with Frans Lubin and Wim Boshuis). In '72 only the GTAJ with Boshuis was left.
Team 4711 - Sir >Irish Moss< was a rival team in '71 only with a GTAm with Nico Chiotakis and a GTAJ with Bob van der Sluis who won the nat. championship that year. The team was run by Sam van Lingen, the cars had a much brighter turquoise, exactly like the colour of the Eau de Cologne which is more green.
