I have some data on that:

10624, 250, 20/26 marked "Savage 1920 Model", M54 (knob on right), long blade

10872, 300, "Savage Model 20", M54 (knob on left), long blade

The change appears to be between those two serials. Earlier serials on right, later serials on left.

You have narrowed it down more with the 10640 serial.

Did they stop using the early style when they changed the stamping to "Savage Model 20"? We have 232 rifles to look for to verify one way or the other.

PS... the "Savage Model 20" is on 10727 but I have no info on the sight.
