This is a neat antique wire cage trap door mouse trap. The mouse enters through the open end into a wire funnel that leads onto a trap door. The weight of the mouse lowers the trap door, which then snaps shut behind the mouse as it moves forward towards the dangling bait, trapping it inside alive. Several mice can be caught in a short time and held in the trap if properly baited. Measures about 16" long, 9" wide, and 6" tall. Great original condition, gently used with age related wear and minor metal discoloration. Still works as intended and the bait wire is still dangling in place. See pictures.
