Been looking for one of these in a good nick for a long time... and finally, the day has come. I was mounting up to go the proxy route and go for the Archives one, but this ticks the box for me.
Lee 101-J from what i assume is the late 60s/early 70s. Interesting how it has the "MR" on the chest pocket and not on the label, as i've seen on some.
If you get the size right, these jacket fit like an absolute glove, i have to say.
