Some vintage PC keyboards have lived a charmed life on the desk of a bank president or others were the first born of their class.. other IBM keyboards were used in more industrial settings and accumulated “battle scars” in their service.  This 1390120 is more than 35-years-old (made in 1987) and has some scratches and some of the keys have been lost (and replaced), and it has cleaned up very well.  Some prefer “fancy” and “shiny”, others prefer “classical, proven-over-time” and “dependable characteristics”.  Good heavy-duty keyboard for someone new to the mechanical keyboard hobby or for those looking for a “Made in the USA” IBM workhorse keyboard with a history.  Selling at 25% discount for the next generation to appreciate.
