I've got my hands on a Stevens Favorite Model 20 Smoothbore in 22 rimfire. I guess it is actually a shotgun, kinda, maybe, not sure. Anyway, I have ascertained it was made between 1901 and 1903 and is somewhat rare but still in pretty fair condition for a 110 year old gun. I have no doubts that it will shoot just fine but it is missing the front sight bead. I 've looked at Numrich to no avail. Anyone have any experience locating a bead sight for one of these animals?
