Vintage '40s/'50s Light Beige Pants, Killer Tab Closure Detailing, Crotch Gusset, Perfectly Distressed & Beaten Up, 30 popular x 30

Seriously killer '40s/'50s beige-ish/bone white trousers in perfectly distressed, well-worn vintage condition! There are signs of regular wear and washing. Structurally, these are totally sound! There are a few faint discolorations, some spots popular here and there, some darker scuffs on the right side of the seat. These were once hemmed up, and then the hem was let out again. There's a small mended fray at the bottom of the fly. Otherwise no major flaws to note.

No tags or labels present. Not sure what this fabric is, but it's pretty amazing. Obviously well worn and super soft and comfy. It feels like a midweight, sturdy cotton twill, but I'm not positive. Such a great super light beige / bone white. Metal 7 inch Gripper Zipper fly with an A-Kay metal slide closure inside the waistband, topped with that killer tab detailing! No belt loops, no actual waistband! Two front pockets, back slit pockets, the left has a button closure. Killer gusset detailing in the crotch.
