The old translation was closer to what one found in the Episcopalian Book of Common Prayer than it was to the original Latin.
Tough to say for some of the prayers. More like 50 years ago, no one was really concerned with the wording of any translations because the Mass was said in Latin. The English in their missals was merely a guide. But it did differ from missal to missal.
For example:
Before the Minor Elevation:
Interlinear:* Per quem hæc omnia, Domine, semper bona creas*,
By Whom these all, Lord, always good things you create,
sanctificas, vivificas, benedicis, et præstas nobis.
You sanctify, You give life to, You bless, and you give to us
EC Missal: By Whom, O Lord, Thou dost always create, sanctify, quicken, bless, and bestow upon us all these good things. (also Fr. Lasance)
St Joseph: Through Whom, O Lord, You always create, sanctify, fill with life, bless, and bestow upon us all good things.
My Sunday Missal: Through whom, O Lord, Thou dost ever create, hallow, fill with life, bless and bestow upon us all good things.
St. Andrew: Through whom, O Lord, Thou dost always create, sanctify, quicken, bless, and bestow upon us all these Thy gifts.
ICEL 1: (1967) Through him you give us all these gifts. You fill them with life and goodness, you bless them and make them holy.
ICEL 2: (2011) Through whom you continue to create all these good things, O Lord; you make them holy, fill them with life, bless them, and bestow them upon us.
