Sheridan sights
At first the rear sights were soldered on, until sometime in 55 or 56 I think, then came the single screw, then the two screws. The screw bases departed sometime around 1970 or 71.
The BlueStreak in the picture has the soldered-on base, the Silverstreak has a single screw in one side with opposing dimples on the other.
