Bracket alignment note with no released measurement

I found a photo of our old gusseted bracket held in its welding fixture, labelled alignment good. The next inspection sheet rejects the released bracket, and a later sheet passes it after correction. We are preparing an FR5 study and somebody has used the photo as evidence that the fixture already works. I want the study to show what is actually known. The photo has no measurement or drawing revision attached. Which old checks could establish a useful starting point?
