Good Question, I am guessing it was quite High, like 1500
Here are some links to VOAs performed by Blackstone on some older motor oils.
Are there any links to VOA's of popular motor oils used in the 60's and 70's
As stated. I tried a search but did not come up with anything.

Here's some data I collected for some SG and SH* oils.

Yup, levels were typically around what we see in a full-SAPS Euro oil, but of course some were higher and some were lower.
Before the mid to late 50s or so however, oils had little to no Zddp, because the valvetrain pressures were really low, so if you have say car older than that they will run merrily on modern low Zddp Mid or even low saps oils.
Although that doesn't mean a good full saps oil wouldn't add some protection.

ZDDP was first discovered to be a good, cheap, detergent/dispersant, I believe in the 1940's. Later. I believe the late 50's early 60's, it was discovered to have good anti-wear properties.
