Here's the Indestro equivalent to your "Ideal" set:


Curiously, it appears your Ideal 15/16" x 1" wrench is punched with a
square hole (presumably to be used as a tap wrench) instead of the round hole in the others.
This exact same set was also marketed by Sherman-Klove and New Britain Machine Co. (and others), and I am in agreement with Private Lugnutz: it's more than possible they were all stamped out on North Kildare in Chicago by Duro Metal Products Co.
