all L1A1 rifles have the three selector positions....british or australia. the selectors have a "paddle" like safety for semi-auto and no "paddle" for FA. most all of the australian L1A1's came from singapore police.
So do the C1's. All recievers have the notch cut for the automatic position for ease of making the lowers. The extended foot on the safety lever was not the only difference between the semi and auto versions.

The "make sense" comment at the end of my post was sarcasm.
