vintage mens levis 501-0155 denim button fly jeans 36x32 1970s?.

I am not dating or Levi’s expert but from my research it was seeming to indicate that these were from the 1970s? I can’t be sure so please see all photos and for the best idea of condition. Please be aware that because these are possibly up to 50 years old they do have a bit of an old smell. I do not attempt to launder vintage Levis as I don’t want to compromise the integrity of the denim, so I’ll leave that up to the buyer. Sold in as is condition. Also note that Well the size is 36 x 32 the measurements on these vintage Levi’s don’t seem to always match up to current sizing so I have added measurements straight across the waist being 16.5” and from the crotch to the ankle which measures 27”

Also please note there appears to be a repair in the crotch area.
