1940s work jeans with an unbranded top snap and donut button, crotch rivet, and back pocket rivets
I have seen a lot of sears branded products such as Hercules, drum major and strong reliable use this snap so it is possible it is one of those brandings.
the jeans are heavily worn faded and work stained throughout. The thighs have been fully lined and patched. Any and all other holes have been patched repaired as well
the cuffs have denim wrapping the hem that is an original repair.
