This is a SunTour V GT (4900) branded up for Vista by simply changing the embossing on the  outer parallelogram plate.

The date of this derailleur indicates that Vista were possibly own-branding quality SunTour derailleurs even before Schwinn had taken the historic step of own-branding the Shimano Crane as the Schwinn GT300 Le Tour .
