Thanks for the excellent detail pics.
Both jackets are almost the same age, because both are Made in USA so after 1975 (before it was Union Made, and before 1969 it was 101-LJ for the regular StromRider ).
And both are the 220 Lot series so I guess both of them at end 70-ies or very early 80-ies but for sure before 1986, when they added 2 side pockets.
And it's true, almost no detail infos on the internet.
I'm out in the mountains but I could check back some more details in some books about the different time periods of the patches.
And your never washed Lee Storm Rider denim jacket is really fantastic.
I would be more then happy to own such a beauty!!!!!
