I found three of mine on eBay.
In addition, I ordered a new printing of The New Roman Missal from Fr. LaSance (Christian Book Club of America, PO Box 900566 Palmdale, CA 93590)...but doggone if I can remember where on the net I purchased it!
(Google might help).
The 1962 Roman Missal (Latin-English) is also an excellent version, and the one most TLM Indult masses go by.
List of Christian Book Publishers The ones marked with a "V" carry Catholic materials. Most of these have links. For the one you mentioned in Palmdale, I've found several references to it but from the link above, here's a direct link that gets you into their Bookstore.
Then there's this one: 1962 ROMAN CATHOLIC DAILY MISSAL
Hope this helps a bit ...
