Okay, this took longer than I meant for it to, but here are some additional photos to help identify the "Elgin."
I take it these are those Alemite fittings I keep hearing about?

I tried sanding off more of the paint under the bottom bracket to see if any other numbers or letters would show, but nothing else revealed itself.

Some close-ups of the rear hub.

Also, just to put it out there, as I was replacing the tubes and tires so I could get this bike rolling, I made a few discoveries.
First, the inside of both the rims are clean! Whether these are the original hoops or not, like the rest of the bike, they're nearly rust-free! Shiny, even!

Next, I found this inside the back tire. It even still holds air! (I took it out and replaced it with a new tube, both to be safe and to preserve the original tube.)

Before I replaced the tires, I just wanted to see what they'd look like inflated. The rear tire is actually in really good shape, almost like new! It's still grippy, it has now cracks that I could find, it's still got the mold lines on the middle of the tread! The front tire is not in as good of shape as the rear tire, but it'd look alright on a display bike, I think.
