Midnight, somewhere.
Beautiful scene, but I hate summer with all my heart¹.
¹Except for the ten minutes between 23:50h and 24:00h on 31st of August.
Bah, I just won a TDS220, with some parallel port only version of a comms module.
Paid equal to US$62, with some probe and a Japanese manual.
Lets see if it actually works when it arrives.

I doubt that cable is for sub-sea use, almost all such cables have at least one layer of steel, and much thicker envelopes.
No, they don't. A major design constraint is the need to fit as much as possible cable on a cable-laying ship, and that precludes steel armour.

The TAT-7 cable was steel core, […]
That would depend on the age of the cable; there is no indication of that.

As much as I enjoyed the video, I think you should stop making them... for the good of your TE !
You are too nervous when on camera, at the beginning you dropped the display assembly then tools soon after !
The health and well being of your TE comes first, our curiosity second.... which is satisfied anyway with the still pics...

If it doesn't you'll have your Japanese wife to answer to.

That's 4 or 5 times cheaper than here....I now understand why you moved to Japan... not because of the wife, but because of the dirt cheap TE, THEN only did you start looking for a wife locally, not the other way around !

I don't think 2.4 micrometres of armour is going to make much difference.
For those in London hankering after some rare analogue goodness, there's https://www.bidspotter.co.uk/en-gb/auction-catalogues/ncm/catalogue-id-ncm-au10579/lot-8a8ff439-c79a-4e04-861f-aebe00b9affb
The listing was written by dyslexics; it is a Telequipment DM63 (not 65), i.e. a dual beam storage scope with 4 input channels. Despite my strong dislike of analogue storage scopes, mine actually works sufficiently well that I'm reluctant to flog it.
Now, do we know anybody in/near London who likes analogue scopes, and has some connection to Telequipment?

The TAT-7 cable was steel core, […]
I didn't say "steel armour", I said "layer of steel", because you are quite right that at depth that is usually a steel "strength member" at the center of the cable.
The steel, or on a few very early cables: bronze, is necessary to prevent the length of cable hanging from the laying ship to the bottom of the sea from being stretched or pulled apart.
Air-dielectric coax-cables, like the one on the picture, has the additional weakness of a very fragile cross-section, which is why they were almost never used for sub-sea applications.
Summa summarum: The cable on the picture has no strength-member, steel or otherwise, and the very thin jacket offers insufficient mechanical protection against compression of the coaxial members, so that is clearly not a cable for sub-sea use.
In fact, I'm not even sure it is a cable for direct burial, it might be designed for use only in conduit.
I'd be curious to know what conduit. I'm also curious to know why there are also PCQ wires.
PS: If you want to to read about the challenges of running coax under the Atlantic, the Bell Systems Technical Journal has excellent articles from the entire history of that practice.

If it doesn't you'll have your Japanese wife to answer to.Naaahhh... at that price it's easy to justify. Even if he can't get it working he can part it out for profit, or parts mule it to make even more money on other units.
More likely she'd just ask him to take her out for sushi when it sells.

That would depend on the age of the cable; there is no indication of that.
There are many indications of the age, notably a plastic sheath over paper insulated pairs and but plastic (rather than foam) disk coax.
I would say first half of 1960'ies.
The cable being UK Post Office and the post-war material scarcity means that it could be younger than that.

Yes I am still emotionally damaged from the last two Telequipment ownership sessions.
