Jacket with no label

[EmoHermit]

Hi there! We are renovating my Mom's house and I discovered this pretty awesome looking jacket, but it has no label, tag, or even marking on the buttons. I know it has to be from the 70s, she once had a London Fog coat but I researched LG and they always seemed to have a label. Any help would be appreciated. I'm pretty good at researching things but anytime I tried to describe the design on the liner it came back as a flag of some nation.

Cute jacket, I'd be happy with 70s at a guess. I'd describe the liner as quilted with a geometric pattern. You could even say a foulard pattern if it is silk or silk blend. Do you know the fabric of the lining? are there any labels at all? Internal & external pockets can have them for jackets. Even on the lining under the shoulder sometimes (usually for size). Could you take a picture of it laying flat? it's difficult to tell the shape with the angle of the photos. It looks to be pretty straight which was common for 70s jackets

I can get better pictures soon. It has absolutely no labels. I searched it, my fashion savy wife who wanted to prove me wrong searched it, even my redneck bff. Its crazy because there's absolutely nothing, not even what material or what size. And it doesn't appear the label was removed because the jacket is immaculate. Will get better pictures ASAP.

With that collar, I'm thinking early '70s. Lovely lining.
