Picked this up over the weekend because it is 12 inch, bigger than I have seen before, and with more detail in the markings. Opens to 1-5/16 (+32)
Note the logo, this large, you can see it is the older line segment style, also the horizontal lines go from 2 lines to three. The hang hole not flush with the end of the handle is also very uncommon....
PS: The 'M' next to the (Y) and next to the hole are user marks
