I have an old Ranger, 22 S. L & LR, pump with smooth wooden pump grip, 24" octagonal barrel, serial # 3902K. There are no other markings on it.

The take down screw on the side is missing, and someone replaced it with a screw and washer. I've attached links to 2 pics (couldn't figure out how to embed them sorry!).

From what I've found, this is likely a Sears version of the Savage 25 made in early 1920s? Is this close or is there anywhere you can point me to in order to find out more?

Does anyone have a lead on where I can get the missing screw, which ones would fit my Ranger, and does it simply screw into the right side of the gun?

Thank you and I appreciate your patience with the newbie! Dan...
