M1 trigger mechanisms that are complete with a good safety. These particular trigger housings have been made unserviceable by positioning a drop of weld attaching the hammer to the housing and another on the top or the bottom of the sear rendering the trigger inoperable. The drop of weld varies in size from housing to housing. Otherwise the housings are in good condition. Expect scattered surface rust, housing assemblies come with either milled or stamped trigger guards, no choice.
