That's some shot of ZDDP, forgetting about the CC, by today's standards they'd say it is corrosive to engine internals. It wasn't then?
 
Wow, that has a lot more adds than I thought. As usual for that period, though, far more anti-wear zinc and phos in the mix than any detergent additives.

Lot thinner than I thought it would be as well, just barely a 30-weight.

To be honest
I was surprised it came back even close to a 30W
It seemed very thin out of the can
 
It could be considered a "build" oil or an assembly lube to coat say cam shafts and bearings for subsequent run-in.
