I am using the top one now, it is my first time using one, and its amazing. Testing them, but so far they all work.

Thanks! This is my first foray into Model M's, I'm reading up on the WIKI. Are there any real differences that make one better than the other (1391401 vs 1390131)?
That's what I've decided to do, just take them apart and clean them, restore the original missing pieces.
Hah, yeah, same for me, I was born on a Sunday. I think my brithday would've been JUST outside of square-badge territory, though (Aug 1987).

It was a seller with only 2 feedback, so I guess no one else bid on it or it wasn't very high up in the listings. Perfect condition, with the super long coiled cable too.
Edit: Maybe there is hope yet, Clickykeyboards has sold a Sept. 1987 square badge 1390131 (gotta have those lock lights) in the past: http://clickykeyboards.com/product/1987 ... 23-sep-87/
