That's the first release of PWB. However, they took delivery of their first PDP-11 in 1973, which is when the PWB efforts began as part of the BIS or BISP business unit (I have conflicting sources on the exact name). After my talk is complete, I'd planned on going back and trying to piece together release timelines as well, since although efforts happened starting in 73, releases, as such, don't seem to start for another couple of years. I suspect that when the number of groups being supported was small, the overhead of a formal release cycle likely wasn't worth the benefits (but have no documentation from the early days to prove that).
