Unknown open end wrenches

Does anyone recognize the maker of these wrenches?
I don't see a name or logo, they just say Forged Steel U.S.A.
The reverse side has the metric size.
ex. 1" says 25 m/m on reverse.

Late to the party as usual, but here's a Hy Bar I just acquired that doesn't look like the ones in this discussion.
It has the dual metric/inch identity.
An appealing little wrench, IMO.
