Not so easy I’m afraid, if English is your desire.
There are two components. Well three really: the psalms, the lectionary and the responsory.
For the psalms, I know of three choices: the Psalterium Monasticum (Latin only), the Psautier Monastique (Latin/French), both in print and available from
www.solesmes.com. These are for the post Vatican II Office. So the psalms will be from the neo-Vulgate. However they will have the correct psalms in the correct order, with the correct antiphons (noted for chanting).
The third choice is the Breviarum Monasticum. No longer in print alas. I have a used copy (gift from my spiritual director), but not for sale
You may be able to find one on e-bay. Good luck, rare as hen’s teeth. Latin only.
For the lectionary, if you use the current lectionary you have a choice between the 1 or 2-year. The 1-year is easier. You can simply use the readings from the current LoTH’s Office of Readings. It will also have the correct responsories for the post-Vatican II Office. For the two year I only know of sources in French (I use it because my abbey uses it) or Latin-French; moreover the post-Vatican II responsory for the 2-year remains, 42 years later, incomplete.
A sort of half-baked option would be to use an abbreviated office of Vigils (we have returned to the original name for Matins as described in the Rule of St. Benedict), from Benedictine Daily Prayer. Shorter psalmody, and the second reading is biblical and not patristic, but to overcome that you can always use the readings from the 4-volume LOTH.
If you can handle French, you’d have greater options
