I was checking out NB on AA.  Found this nice little flip top set identified as None Better No. 3.

It is exactly like one of mine--right down to the attention to detail, the crosshatching, and the size identification style--except that my ell is 6 1/2" long rather than the 7.4" in the AA one. 

And mine is marked Indestro (in script) CHICAGO.

Do you suppose one company made the set for the other?
BTW, doesn't the AA set look like it is missing a small socket, likely 7/16?
