I have digitized some tapes that I had of the late Fr. Conrad Altenbach (d. 1901-1985) from Wisconsin.  There are ten talks in all, 45 min. each.  He was strong on the doctrine of No Salvation Outside Church, and also blasted the New Mass.  If there were more priests like him at the time of the Council modernism would have been smashed in America. He mentioned that in 1973 he got together with priests from eight other states and their intention was to preserve the Latin Mass.  I am sure Fr. Wathen was in that band, but I would be interested to know the others. 

These files are too large to upload, so I just put up a link to my Substack Page:
