The 1945 Saint Andrew Missal, published by St. Bonaventure Publications.
I haven't seen one of these in years. I purchased one back in the Seattle days - when I was still a novice with the old Latin liturgy. At that time, I hadn't the slightest clue about the Holy Week changes and the precursor reforms that would eventually climax in the Novos Ordo Missae of Paul VI.
This book is one of the most accessible means by which to gain some familiarity with the Missale Romanum before the idea of liturgical reform was seriously acted upon, an open window into the pre-modern Latin liturgy.
I have very fond memories of this title. Sadly, I'm not entirely sure what became of it - in storage, lost or misplaced are all viable theories. For a time, however, it was a go-to favorite.
