I’m talking about the terms used when Tekes first started coming into the US. The Russians themselves and Americans never used the term “buckskin” – they used “dun”.
I have no idea of the time line in color testing (genetics), but when I hosted the American AT registry conference some 6 yrs ago, they were still referring to genetic buckskins as “golden dun”.
Kinor was 3 then, and I knew what he would produce would be a buckskin (he was a cremello), but imported Tekes were still being called “duns” if they seemed to be buckskin in color.
As I said, I haven’t been involved with the registry in quite afew years…just sayin’…
