Not crazy 70's vintage looking but has really cool oversize angled flap pockets.. Has a leather "Gucci" label. Had a neat Hermes-esque chain link pattern print on the inside back where the Gucci label was sewn onto. Made in Scotland by Macintosh - rubberized cotton. Guy I bought it from worked in the fashion industry for years. I bought the infamous Polo cashmere bear sweater from him last year. He purchased the jacket from Neiman Marcus in the late 70's - he thinks 77 or 78. It's at my brother's house currently and he said he can't find a size tag on it so I'll measure it tomorrow. From what I remember it looked to be about a Small-Medium.
That looks like a pretty generic MII tag., not sure if you can deduce who made it by that... .
