Title: Virtually unknown 1st-gen Model M, p/n 1391240

IBM 1391240 RARE VINTAGE CLICKY MODEL M KEYBOARD WITH PS/2 CABLE WITH WARRANTY  (http://www.ebay.com/itm/IBM-1391240-RARE-VINTAGE-CLICKY-MODEL-M-KEYBOARD-WITH-PS-2-CABLE-WITH-WARRANTY-/111756423610) (eBay)

It's $275 BIN/OBO, so I'm not suggesting anyone rush over to buy this—but it is sufficiently unusual that I thought I'd post about it.

This p/n isn't in Wikipedia's or Deskthority's Model M lists. There are no references to it on DT or the general Web (that I could find). There's only one brief reference to it here on GH (https://geekhack.org/index.php?topic=60524.0): Someone found one last year and no one knew anything about it.

It looks like a 1390131, except that:

What's more, it looks either unused or restored. (The feet aren't even dirty; I don't know about you, but that's the first thing I check... If it's the same board the GH member posted, I'd assume they knew how to clean it up.)

Isn't it remarkable that unseen Model M p/n's can still be appearing? (I'm adding it to WP now, so the entry you see will be a new one.)

Now that I'm not in such a hurry, I realize that interior photos are included. There's a bit of discoloration on the bottom plate—which could be found on an unused unit too, of course—but everything else is indeed quite clean. So this is someone with a 5.5mm thin-wall hex driver.  :?)  The description also says, "All of our items are clean". So I'm guessing it's been restored. Pretty nice, in any case!

Does it belong to someone here?

There is a picture of SDL to PS/2 cable, so the T likely doesn't stand for terminal, right?

Well, the 1390120, from the same period, is considered a terminal board, and it's PC-compatible... What else could "T" stand for? Toaster?

Also, the corner is pretty badly damaged.

You're right, I didn't even notice. So obviously restored, then.

Used.  I don't see anything restored about it.

The staining on the backplate looks like potential water/moisture damage, and there's rivets missing on numpad side.

Well, "cleaned", I should've said. Again, when I posted this, I'd seen only the photos that were visible by default, and from those it looked like it could've been unused or restored. Prithee cuttest thou me some slack, dude.
