Do we know, when Levi's had used raised belt loops and when not?
Was this only in the war models?
I had a look at the pics on the TCB website.
On the vintage 30s (on the bottom) we can see, what looks like raised belt loops.
For the 40s/WWII model I can't really tell. In the first and last picture, they look raised. In the second one they look flat.
I think, the text on the left in the second picture says, that they are raised (中高). Not sure, though.
