I bought this stapler in April 2011 to replace an old Arrow stapler that was "broken".  Well, it turned out it wasn't really broken after all.  A friend had used my old Arrow and lost a nut off one of the bolts holding the thing together.  After I had purchased a new stapler, I was digging through some boxes in the shop and found an old nut of the right size to replace the lost part.  This fixed the old Arrow but I had already bought the new one in the interim so I put the old one away as a backup.
