I'd go with doubtful, since I'm not together all too sure. I'm definitely not in the Dimond camp that'd suggest Catholics who were unaware of the Crisis brewing and received Confession, Last Rites, etc. from a Novus Ordo Priest were damned to Hell just because they didn't have perfect knowledge of deeply complex issues that not even the most well-educated clergymen and theologians can agree on. While these days the heresy in the Church may seem blatant, for decades after Vatican 2 a Catholic could go to Mass every Sunday blissfully unaware that anything was wrong. Most Catholics never even heard of Archbishop Lefebvre. 

Invalid!  Chapter 12 of Daniel states the Holy Sacrifice of the Mass will end (continual Precious Blood).  Martin Luther gave it a good head start to where we are now.  All of those who say the invalid, are publicly heretical.
