These pictures are from a rather beat-up brochure from the mid-1960's, most likely 1964, and features Mariner #125.  The catalog also features the Day Sailer, Rhodes 19, Tempest, Javelin, Widgeon, and Sprite.

Thanks to Thomas Armstrong for permission to have these pictures on my website.  Be sure to check out his blog at http://70point8percent.blogspot.com.
