A solid double-assist from Down Under - thank you both Gav and Bryan.

I performed a cursory search, I found that almost all the fids I could find were notched. The lone exception I found was here, which closely resembles my own.

I, too, agree that the crude etching seems to resemble a "strong arm," but until the fidentification, could not place it in context...
