Processing 62-year-old expired E-3 Kodak Ektachrome film - Is it possible?

[curvedwallride]

I was cleaning out some of my dad's stuff and I came across 7 rolls of Kodak Ektachrome 120 film shot & expired in 1963. I'd like to get these rolls developed, mainly b/c I'm extremely curious what is on the film. Many say "Model" or have names of models and friends. My mom told me that before my parents met, he had been in a "photo club" that shot "risque" images.
But since they are so old, I don't know if it's even possible to get the film developed.

So I have a few questions:

Since it's already 62 years old, probably not stored correctly, and I have no idea what the ISO is (not on packaging), can this film even be pushed enough to produce an image?

From my understanding, E-3 processing has disappeared and processing the film probably isn't possible anymore.
Are there any other alternatives to E-3 that can achieve the same process? If there are any alternatives, where can I find the chemistry?

How many stops do I need to push this? 1 stop per decade right? Does this film even have that much latitude?

Does anyone have any other pro-tips to get this film developed?

E2 and E3 are prone to severe fading (E4/E6 as well but not as bad). This film might just be blank (clear) no matter what method is used.

What is the film ISO?

There should be an ASA (ISO) number somewhere on the box or the paper tape on the roll. 100-200-400

75 rolls of unprocessed film was found recently from San Fransisco from the 1960s. They are developing it.

What is the film ISO?

I think it was 32 or 50? Highest would be 160 but the box would say "High Speed".

Find a lab willing to do a clip test on a single roll. Think it unlikely it will produce results--but who knows?
