Now, I’ve found Eve Plumb as Jan with long blonde pigtails in s3e1=pic 2 (and s3e2 ?) She looks younger than 12 yo, maybe filmed earlier? Also showing younger Cindy on the right on pic 2. Maureen McCormick probably don’t had braided pigtails.
The pants of Jan with a belt looks quite tomboyish. Yellow was also commons for a boy in the 1970s. Good western setting and riding on mules.
Rating 7-8 for Jan (Pic 2 looks somehow better than pic 1). Still needs to be checked for other girls and pulling pigtails scenes.
Main entry also showing Cindy and another girl at
