We hold a number of Maronite antique prayer books, some of which are still used in the Liturgies today.
Ned,
Are you anywhere near

Many years,

PS - As I was thinking more about this, 2 things came to mind
... you do realize that your chances of finding a pre-1962 Maronite liturgical text in English is pretty much nil? There were no Maronite canonical jurisdictions in the English-speaking diaspora until 1966 as memory serves, when the Apostolic Exarchate was erected for the US. Bkerke hadn't published any new official text in something like 400 years, until about 1990.
There was a 1935 text called "The Syrian Maronite Mass in English: hymns and answers of the choir in English characters, explanation of ceremonies, Communion prayers : for the use of our Lebanese and Syrian youth" The author was P.F. Sfeir, a priest in the US at the time, I believe. It was published out of Detroit by a house called McDevitt. Good luck finding a copy of that. Other than the heritage center, I'd suggest your only chance would be a university library - (doubt the SSPX) - or an elderly Maronite priest with an inherited book collection.
... also, not sure why you chose '62. There were no significant (if any) liturgical changes in the Maronite Qurbobo/Service of the Divine Mysteries in the immediate aftermath of VII.
From late 1968 until mid 1969, while in the Army, I worshipped with a Maronite parsh because there were no Byzantine parishes anywhere near my assigned post. Absolutely nothing had changed from my first exposure in about 1960, nor any of the times that I had attended a Maronite temple in the decade of the 60s.
Either the Exarchate or its successor Eparchy of Detroit of the Maronites published a small series in the 70s, which probably documented the first changes. (I think there were 4 or 5 texts, each devoted to one of the Maronite liturgical seasons).
Many years,
Neil
