Vintage 80s Levi’s tan cargo pants size 30x34 Made in USA

These are a first for me. No exterior Levi’s marking, even the snaps are plain. Early conception of cargo pants, not really influenced by military cargo pants, has a two layer waist pocket system with a single snap pocket on right rear. Tag says 30x34 and they still measure true. No holes or stains. Zipper stamped Levi’s.
