Probably not the best place to discuss this but when did IBM/Lexmark start using that style of sticker for the num lock lights? I had always assumed it was for late model rubberdomes but clearly this isn't the case.

There are a lot of differences in the Greenock-made Ms.
The later ones had ABS spacebars with grounding straps, for one thing.
Ask someone who knows more about that factory than I do.

Hi, I'm the seller.
Don't know that much about the inner parts, but the keyboard feels like the rest of my about 10-12 Model M's. The interesting thing, in my opinion, is the european / ISO key layout. They are not very common in NIB condition. I have a few for sale right now.

Really strange to me. 1391407 model number with a 42H1292 design. The cord is permanently attached to it? The date is right for the 42H1292. Does it have a detachable cable? This is very odd.

Danish/Icelandic 102 layout? ???

Fohat, that rear label is a sticker. The spacebar should be yellowed, I agree. Unless they changed the type of plastic they used on the newer model? I don't know.

The current Unicomps and the older 42H1292 keyboards have the same controller on the upper right side. The membrane actually is different, but the keyboard is still buckling spring. I would think the QT versions (Rubberdome) have the same controller too. You have to be aware of that. The model number is usually the giveaway. In this case, it's an enigma.

Regarding the cord: Yes, it is attached to the keyboard.
One other thing, I have noticed in my collection of danish ISO IBM Model M's: The cord on my 3 1995 editions are all coiled - with a smaller diameter than the usual coiled cord. I have only seen that on my own keyboards.
And as we are speaking of IBM Model M. I have noticed, that my 5 keyboards between 1986 and 1991 have a little less pingy feeling than the newer ones from 1991 and upwards. Perhaps it is due to the fact, that my newer ones all are NIB, while the other are used.

Note that the cable is flatter and thinner as well. That's the standard construction on the M13 cables, as well as all the later fixed-cable M's.

You're absolutely right about the M13 cable. I have just googled some pictures, thanks!

The early Model Ms were made with a heavier steel plate, which tends to give them a more solid feel and could also help explain less pinginess than later versions.
