The older Berettas don't have this kind of standard marking. The older S2 and S3 guns contained the model designation. The S3ELs and S3EELLs from the 1970s have a serial number on the trigger guard. I'm not sure when/if Beretta standardized the trigger guard designation marking.

I also have the old thread from 2004 with the SO discussion, but is a pdf file and I don't know how to post it. Anyone have any ideas?
