IBM 1394946: Industrial Model M

This is an “industrial” IBM keyboard. That means nothing about its construction; it is very much the same thing as a 1391401 or other 101-key Model M, but has unique colouring to match IBM industrial computers.I got this keyboard in April 2010 from an eBay auction for two units together, untested. I took a rather expensive gamble but it worked out well…because they were untested, they went for a reasonable combined price, and when I received them I found they both worked flawlessly and just required cleaning. I quickly sold the second one for half of the original bid and shipping.
