There is a bigger email component to this post further down.

I got an email today saying that they could tell I had recently used
Skype ver. 7 and that support for that was ending in November.

Update Now.

I almost did that until I checked my Skype and it said it was version
12! About this Version: Skype 12.1815.210.0

My Skype does *not* say "About this Version:", but just "Skype TM
Version ...", so you should probably re-check what you did.

Is this an old phishing email and they forgot to change 7 to 12?

I don't think so. The first (from bottom to top) 'Received:' header
looks legit, i.e. directly from skype.com to microsoft.com:

Received: by mta21.email2.microsoft.com id hmef9q163hss for
; Tue, 2 Oct 2018 16:32:13 +0000 (envelope-from
)

The first header is hard to fake/forge, so if it's legit, that's a
good indication of the message to be legit.

But I went to Skype Download and by golly, it wants to install version
8. Not 12 or 13.

Correct.

What's going on? Do I have version 12 now or version 7?

I'm sure you have 7. Just go to (Windows) Control Panel - Programs
and Features (or whatever is the Window 10 equivalent) and check there.
Mine says 7.40 iunder Name and and 7.40.103 under Version.

So, does this look real? How suspicious is it that they tried so hard
to hide the headers? The Skype page about phishing says that
email.skype.com is one of their 7 genuine domains, but can't a phisher
use any from address he wants?

I don't think anybody hid anything. It's probably you not knowing how
to get Eudora to show you what you want/need.

And yes, it's trivial to fake From:/To:/Cc:/Bcc: etc..

P.S.
On the phone, the updates happen automatically I assume and I don't
know where to find the version number of any app I have. What's a guy
to do?

Settings - Manage apps - tap on desired app, i.e. Skype - Bingo!
