This Infallible trigger is fron a LC Smith Crown grade 20ga...note that it's a standard Infallible...All the talk about Worrest's first unsucessful patent has given rise to stories of Worrest being employed by Hunter Arms at one time...or...about LC Smith's with Infallible triggers being hollowed out...and more...they're all nonsense...don't take my word for it, look for yourself...compare it to the drawings from 829453
