Greetings- and Happy New Year!

I have a S.A. model 1907 .32 auto pistol that I have disassembled and can not reassemble.

Is there a "good" reference book or directions on accomplishing this task?
The Savager Arms site shows an exploded view and written directions but the part I need to place is not shown and the directions do not detail this piece. The
safety bar, a narrow bar that fits to the left side of the frame and near the sear trip and the sear trip lifter. I do not know which way it goes in, the correct position is not illustrated.
Best to all!
Steven
