Update 8/10/07 - here's the answer:
Intruder alarm, screwed into a door or window frame, a percussion cap is placed on the nipple and black powder goes into the barrel. When the device is triggered, the spring powered hammer hits the percussion cap, which fires the black powder, scaring away the unwanted visitor. It could also be attached to a tree and rigged to a tripwire for an outdoor alarm.It was a stumper! No one got it right, though "Ye Olde Stapler" is an excellent guess!
