New Strap Slot 3/16" Reach Style No. 448 - very heavy duty in original box
£13.32
The photo of the box end is the only info I can find on this slot punch. The slot punched out on the box flap is what it looks like. 1/8" wide and 1/2" long. It looks a lot like the conductor punches used on trains, but I do not know for sure.
