MicroSoft Windows NT Workstation Software
New and Wrapped including COA
These were the version distributed with new PC's and are selling on eBay for £10-£20 each.
I have 9 of these and they are one per person.
Only ask for these if you know what they are, actually have a use for it and can pick it up, I'll leave them in the Rock Ferry shop.
