I bought this jacket at a thrift shop yesterday, and although I like the jacket regardless, I'm trying to date it and have read some conflicting information. It has a small "e" on the Levi's tag, double stitching next to the bottom button and 2 pockets on the chest, with none on the bottom. These features seem to indicate, according to my research, that this jacket was produced sometime between 1971 and 1985. However, it seems to look a little too "newish" to actually be that old. Are there any Levi's experts here that could help me identify it's age?
