I found the sources to V6, V7, various BSDs thanks to
www.tuhs.org (The Unix Heritage Society).  Boy! Was I wrong!

V7 tar does nothing special for root, neither do various BSDs
(I checked upto 4.3BSD-Reno -- I even compiled the reno tar
and verified that as root umask is obeyed).  I don't know at
which point root got special treatment in tar at various Unix

My apologies to Maxim and others for confusing them.
I plead (hopefully temporary) dementia!
