The model appearing in this loop film with John Holmes is Anna Lee Roper, an early 1970's starlet who appeared in a handful of one-day wonders like "Waterfront Honey." She was also a print model in Eros Goldstripe publications like "Aggressive Gals," and "High Heels." She appears to have been a natural redhead but often wore wigs of various colors as many starlets and print models did during then. Someone ought to update this IMDB listing as well create a filmography.
Note: She had a scene in the Alpha Blue Archives compilation "Golden Shower's of the 1970s."
