This is a rare and very cool pair of vintage 20s - 30s denim work pants / jeans.  They are in exceptionally nice vintage condition and have seen little or no use.  The waist measures 28" and they measure 29 1/2" from crotch to bottom of pants leg.  They do not say a brand that I can see but have a very distinctive top button with antique John Deere tractor and corn field in the background of the tractor.  It is button fly.  Please see photos and ask any questions.  Thank you and have a great day.
