Oliver Plow Identification

This is my grandpa's Oliver plow and we are searching for what model plow this is. I know it was made around 1916, as I have seen dated pictures with this plow being pulled by Fordson prototypes. In these pictures the word 'automatic' is paited on the back of the frame. It uses the same mouldboards as the #7 but is totally different otherwise. The real odd part is that the furrow wheel lifts the plow. I have also sumited a picture in the implement section, but have not gotten much of a response. The picture I posted in the Implement Photos is of the other side if that would help anyone out. Thanks in advance for any info! -Steve Welker Submitted by Steve Welker, from PA
