According to prewarcards.com, the checklists for the 1917 sets Collins McCarthy (E135), Weil Baking (D328), and Boston Store (H801-8) are exactly the same from what I can tell. However, I am unable to find a checklist for the 1917 Standard Biscuit set (D350-2). 
Is it simply an assumption that this set mirrors the checklists of the aforementioned 1917 sets? Or is there confirmation? 
I PC Grover Hartley, and I know there is at least one Weil Baking Co. example in existence (SGC graded I believe), but have not seen anything to confirm any known examples of him in the Standard Biscuit set. Trading Card Database lists Standard Biscuit on his checklist, but there is no picture and the PSA/SGC pop reports don't show any graded examples. 
Since every post must have a card, here is my Hartley PC (I need to update the group pic).
