Difference between Pre-war and SAA

[Banjoman]

Ranger dan,
The SA and Pre War are identical except for the bluing and a CC hammer (standard) on the PW.  The SA comes standard with a white sided hammer.  The SA and the Pre War share the same serial number range meaning that 25003 could be a SA and 25004 a Pre War.  The easiest way is to call and give us your serial number and we can tell you it's configuration.
