Note:  Item has been thoroughly re-cleaned today to reduce the appearance of practically all the dirt and scuffs typical of these keyboards used in industrial environments.  This may be one of your last chances in a while to get one of these!

I also have available an IBM 4704 107-key and 50-key Model F buckling spring keyboards and some Model M cover sets, a controller, and a few inner assemblies.

Feel free to message me with any questions!  

An unused IBM Industrial SSK with no IBM logo on top was bid up to $1999.99 earlier this year - see the listing here:

From my collection you are looking at an IBM Model M Industrial Gray/Green Buckling Spring Space Saving Keyboard SSK Model 1395682 from October 1992.  This is one from the earliest years of production compared to the more common year of 1995 and its laser-printed label.

A Deskthority thread mentions that likely fewer than 10 of these custom-built Industrial SSK's are extant, compared to the hundreds of Model M's available on eBay at any one time.  Almost all of these keyboards were probably shredded along with the industrial/factory machine being retired or upgraded.  http://deskthority.net/photos-f62/ibm-industrial-space-saver-t6540.html


My other custom blue keys Industrial SSK sold to a European buyer within 12 hours of listing it for my full asking price of $1,175 earlier this year, and I have decided to sell this example as well.  

As you know this is one of the rarest IBM keyboards due to the significant expense and relatively limited production run of the original IBM Industrial PC's compared to other IBM PC's.  

Not only is this an Industrial SSK but it is one of the only IBM factory-customized Industrial keyboards with unique key caps most likely geared towards a particular piece of software.  

Original-issue custom-function blue keys:  
This particular Industrial SSK is even rarer due to the original-issue custom-function blue keys with commands such as Read/Hold, Main Menu, and Suspend.  In the GH/DT/Reddit forums only a few of these have ever been photographed by collectors around the world.  

Early-Issue Dot-Matrix Style IBM Label:  
This early production run Industrial SSK has IBM's dot matrix style label, which was used before they switched over to a laser printer label.  Most Industrial SSK's I've seen online have been of the later production run with the laser printer label, most often manufactured in 1995.  

Only a few of these factory-customized IBM Industrial SSK's have ever come up for sale and are known to still exist according to eBay and the geekhack/Deskthority/Reddit forums. 

Thoroughly cleaned inside and out but still shows dirt and scuffs/scratches from usage in an industrial environment:  
This unit is from my personal collection and has been thoroughly cleaned inside and out, key cap, stem, and barrel frame, has been fully tested, and works well. The typing feel is very smooth.  

Since being cleaned it has only been used briefly for testing.  Unfortunately this unit still has some discoloration/dirt despite having cleaned it (as shown in the photos). 

Frame appears intact with no significant cracks or chips but has noticeable scuff/scratch marks primarily on the sides, possibly from being used in an IBM Industrial PC keyboard drawer.  There are noticeable scuff marks on the bottom of the unit.  Please see the photos but be aware that these marks may not fully show up in the photos.  All photos are of the currently-listed item.  Some discolorations are also visible on top.  

These mechanical buckling spring keyboards are built to last - my main one still runs 100% despite being used since the mid-80s. 

No bolt/screw modifications have been made to this unit:
This unit has not been bolt/screw modded.  Great if you prefer to buy an unaltered keyboard and keep it as it is or modify it yourself.  

Some guesswork on my part regarding this unit's origins:  
Judging from the custom-function blue keys it was likely designed for a specific application of some kind.  
The 1395682 Industrial Gray unit was likely designed to run the same custom-built model of IBM Industrial PC that required custom key functions Read/Hold, Menu, Suspend, etc.  
I remember when I bought the currently-listed unit my recycler source told me he pulled this unit from a 1990s-era IBM Industrial PC system.  

Buyer has a choice of one cable (included but not pictured): either a used extra long SDL to PS/2 cable or a used regular-length one. 
Ships just about worldwide.  I have been on eBay for over 10 years and will pack this order carefully.
