Hereford Brand Tex Tan of Yoakum serial number help? Value?

[AbsoluteWA]

A woman brought her deceased husband's saddle in for me to sell and I'm trying to learn more about it and, hopefully, someone can give me an approximate value. I come from the English riding world and my knowledge of western tack is limited.  It's a Hereford Brand Tex Tan of Yoakum. She said it was here husband's show saddle.

The serial number is 76 G 122-69691

76 is probably year 1976.   The white buckstitching is a holdover from the '60s and early '70s.  Later ones had brown buckstitching, or none  The double skirts are in fashion, so that's favor, value-wise.  It's also not real dark brown, which is good.  Don't put any oils on it because it will probably turn dark brown again.   I'm not western, either.  If it's a 16" seat, I'd try for $500-$650.   15" would be worth less.   Herford had a dark chocolate 16" model in 1980 that was pretty much the same as this one, except no white buckstiching.
