Acronym expanation

NIB

New In the Box (NIB) or sometimes called Mint In the Box (MIB). These slide rules are the hardest to find. They look as if they just left the factory. And they are in the original packaging. Due to long storage (it could be up to 30 or 40 years), the boxes will show some 'shelf ware'. That is there may be some scuffing on the boxes, or some slight 'browning' of the paper. The manuals may have a permanent crease as a result of being folded in half for all these years. The number of these NIB or MIB slide rules decreases each year.
