They were found in the old attic of a homestead house on our property, we believe they have never been touched since put in that box. Besides some dirt and grime they are practically untouched with just some minor wear and tear around the knee and lower pant leg.

. Looking for help identifying year/model.
Features:
Big E single-sided tab
Cinch back
Hidden back pocket rivets
Redline selvedge
Leather patch
Button fly
Found with old papers in pocket including a July 1937 insurance notice (not claiming that dates the jeans).
Any idea on era/model?
