My own guess would be to add another button and button hole ( upwards, to shorten the lapel) and see if there is undamaged tweed beneath those suede patches. I suspect the jacket is from those wild years in the 70s, when "country gent" looks prevailed in the most urban of settings. But I think it is a nice tweed and it is big enough, which so many vintage garments aren't. If I were in Edinburgh, I'd pop in and give it a long look.

I have been trying to study on pocket ( and pocket flap) placement. I THINK I have noticed that American style tweed jackets may tend to have lower pockets than UK styled ones, especially "hacking" cut ones. But that is just a guess. The importance is what happens when you shorten the jacket for kilt wear. We have all seen them where they looked obvious, but I have noticed a few uncut ones that seem to be able to withstand some editing...
