Huh. Well this seller is enthusastic. http://www.ebay.com/itm/BNIB-ULTRA-RARE-SCOTLAND-UK-MFG-1997-IBM-42H1292-CLICKY-KEYBOARD-MODEL-M-/280874409144?pt=PCA_Mice_Trackballs&hash=item41656b5cb8
The seller is wrong. This is not even close to been one of the last  42H1292 M's. Production of these stop in 1999. Proof:

This is why you must research before listing.

You gotta admire the gall, putting the reserve at $150 when it would probably only fetch that in the open on a good week. Then again it is made by IBM and not Lex/Uni so I could be talking out of my behind.

I have had one 42H from Greenock, I think it was also a 1999 model, and it is the only M I have ever had with a controller problem.

Especially unfortunate, since those parts are not as easily interchangeable as most of the others.

Although I got it cheap enough that it was worth it for the keys alone!

Nice. How late in 1999 was this?  If it was past October 1999, that would explain it. As with most products that come within the last few months of a companies manufacture, the product is so rushed that it does not pass the quality check thorughly and may be why the controller failed..
I have heard people "claiming" to have a IBM produced in 2000 but I don't believe them. I read somewhere that the Greenock factory halted production in November and factoy closed in mid-Decmeber of that year. I do however know that M13's were produced until mid- late '98 because they had a contract with MaxiSwitch after Lexmark's contract ran out in '96.
So what this should mean is any  buckling spring keyboard post-2000 is a Unicomp. 1996 to 1999 can mean a very late Lexmark (mostly only Lexington), a Maxi Switch, Unicomp or a IBM produced keyboard (only at Greenock). 1992-1996 means either a Lexmark (Guadalajara or Lexington) or a Greenock IBM produced Model M. Pre-1992 mean either a Lexington, Greenock or Guadalajara IBM produced keyboard.
