Here's a new twist. It just dawned on me that I could check another
property that I own and see what the gas line looks like coming in. It
turns out that it also has the same type of silver fitting. Here
are photos of that one:

That looks like it could be the dielectric fitting as somebody else
mentioned earlier -- the whole thing instead of having just used the
one end as a bushing as appears to have been done in the other case.

That could be correct. I'll have to wait to find out (see below), unless
someone else here knows what it is.

What's the dark section the el is screwed into on this one?

The dark section didn't show up well on the photos, but it appeared to me to
be threads that are eithe part of the fitting or are a threaded nipple that
goes between the fitting and the L.

Don't guess there are any manufacturer marks, of course???

There are no manufacturer marks anywhere.

I went to another property I have today and it has the same type of fitting.
Here are two photos from that property:

The gas company is now going to come back out to the original property (the
3-unit) next week and switch the 3 existing meters over to meters that can
be read remotely (they call them ERT meters, or something like that). When
they show up, I'm going to ask them what the fitting is and what it is for.
I'll post what they tell me back here when I find out.
