All three pics have the same side to the left.
On the 'flat' side the markings only go to 4 1/2.
The 'knobs' are not the same.
They are not the same distance from the ends.
They are not the same distance from the edges.
One is more pointed.
The other is beveled.
Both ends of the rule are short.
One more so than the other.
This rule is severely worn. You can see that it is worn toward the edges and I can feel that the ends are thinner than the middle.
