This is a ‘Victor 4-hole Choker Mouse Trap’ made by Woodstream Corporation, Lititz, Pennsylvania, USA. The double-coil spings, loops and trigger assemblies are mounted on a moulded plastic base.

This was a development of the ‘thread set’ chokers that had been used for centuries earlier. In this trap the springs are held down by pivoting wire triggers.
This example dates from about 1990.
