I was further delighted to then be informed by the same Br. Stephen of a more detailed post about this specific set, which they have only just recently restored.
Apparently the set, which is thought to have been made sometime around the 1920's or 1930's, was made for St. Francis de Sales Seminary in Milwaukee -- which would likely explain the presence of a figure of St. Francis de Sales on the front of the chasuble.
Br. Stephen informs us that the set was restored by Dr. John Lilley of Philadelphia: "The embroidered panels, orphreys, and galloon of the original set were expertly relaid on an ivory and gold fabric closely matching the tone and pattern of the original with a new crimson lining. It was hard to believe that the set was 80 years old."
Here are two views of the chasuble, and one of the tunicle.

Tunicle, Orphrey detail
Br. Stephen notes that "...as the other tunicle, the humeral, and two copes make their way back from Dr. Lilley’s workshop, the St. Francis de Sales Set will return to its place as our principal High Mass and serve the Abbey and the greater glory of God for several more generations." Very good news -- and very good to see these restored and thereby preserved for future generations and continued liturgical use.
As a point of note, Our Lady of Spring Bank has some other vestments that are worthy of note, at least one of which we have featured before, the Pont Colbert Humeral Veil:
One which we have not specifically featured before, however, is the Fort Augustus cope:
