I know your interested in US Made long pattern wrenches but, have you considered Dewalt?
I'm throwing them out there because, i recently picked up an SAE set that ran from 3/8 to 15/16 for like $25 from ACME tools and was pleasantly surprised at their quality. Yes, they're made in Taiwan but, i really like their balance and feel. They are patterned after Proto ASD with anti slip open ends and off corner engagement on the boxed ends. A Dewalt 1/2 wrench measures 8 inches overall. There's no lobster claw open end on these wrenches.
When it comes to non truck brand US made long pattern wrenches, pickings are pretty slim. I'm not a fan of SK long pattern combination wrenches because of that wide in the hips feel on their boxed ends. Williams supercombos are really nice but, get kind of club like in sizes over 3/4 or 19mm. The long pattern NAPA professionals are nice wrenches but, they're also made in Taiwan. Armstrong and the old Craftsman Professional series wrenches have become extinct.
There are plenty of used truck brand sets on ebay so, you could always be patient and find a deal in time. Good luck in your quest
