Winfield-Hill, the top-order batter, was dropped during the 50-over World Cup in New Zealand at the start of the year, where England finished runners-up to Australia after a troubled start to the tournament.
England opted to introduce a number of youngsters towards the end of former head coach Lisa Keightley's tenure, which finished in September. The likes of Alice Capsey, Freya Kemp, Issy Wong and Lauren Bell thrived but England were left with a dearth of senior players, particularly after their failed home Commonwealth Games campaign.
England lost their three-match ODI series against India 3-0 but won the T20s 2-1 with wicketkeeper Amy Jones standing in as captain with Knight, Sciver, the regular vice-captain, and 37-year-old seamer Brunt on the sidelines.
Jon Lewis, Keightley's successor, expressed his excitement at working with the group on the tour, his first since taking over the post.
"It's great to have Heather, Nat and Katherine back in the group," Lewis said. "The quality and experience they bring can only add huge value both on and off the field. We will manage Katherine back into competitive cricket with an eye on the ICC Women's T20 World Cup in February.
"Equally, for Lauren, it's pleasing to see a player go through a tough period and come back stronger, while demonstrating terrific form at domestic and franchise level. I have been particularly impressed with Lauren's ability to put the bowlers under pressure and score at an impressive run rate in the powerplay."
The 19 players selected will travel out on November 29, with the four ODI players not selected in the T20I squad - Emma Lamb, Kate Cross, Alice Davidson-Richards and Tammy Beaumont, who lost her place in the shortest format for much of the English summer - returning home at the end of the three-match ODI series. Brunt, Winfield-Hill, Sarah Glenn and Issy Wong are only part of the T20I squad while Tash Farrant was unavailable for selection as she continues to recover from a stress fracture.
The tour consists of three ODIs for ICC Women's Championship points in Antigua on December 4, 6 and 9 followed by one T20I on December 11 before four more in Barbados on December 14, 17, 18 and 22.
The T20I series represents the final chance for players to impress Lewis before selection for the upcoming T20 World Cup in South Africa, which starts on February 10.
