This category gathers together items that have a technological aspect - mechanical and electronic. All items are guaranteed to date from pre-1992; most predate this by decades. We try as far as possible to have items in original packaging with all the associated paper ephemera. If this is not the case we will state this in the individual product description. Products, other than those we classified as a toy or electronic game and so have their own categories, include items used within the home, in photography, or are scientific or electronic in nature.
