I would say this is not a style that did not catch on but rather simply an older style of coatee that has like all fashion gone out of vogue.
Are there other images from that era that show further examples of this style? If so, I either haven't seen them or I wasn't paying attention. It may very well be that a lot of Highlanders wore similar jackets in that era, and if so, I'd love to see any images of them!

Yes, Lady Chrystel was my first thought on reproducing this. I should start saving now...
