It was a brand I've only seen in catalogs from Libertyville Saddle Shop in Illinios. But that store went out of business 2 years ago or so. The contents that were leftover were all bought by Horseloverz.
The El Dorados looked like a decent saddle. Probably equivalent to a midrange TexTan or Circle Y of the late '80s and early '90s. That one is probably '90s as evidenced by the silver tips with the conchos, the lighter color, and the smooth jockeys and fenders. I think most of that line sold for under $1000 but that bought much more saddle back then than now.
