A reader alerted me to an article on kreutz.net which deals with Communion in the hand at celebrations of Holy Mass with the 1962 Missale Romanum, and the employment of altars girls.
I don’t have time to translate it from German right now.
Apparently a canon lawyer named Wolfgang F. Rothe, has put out a study of Summorum Pontificum Liturgische Versöhnung.
The book has a preface by Msgr. Camille Perl, Vice President of the Pontifical Commission "Ecclesia Dei".
Perhaps someone who has a little time can drill into this and help the readers.
