Hartley saddles I believe were sold by Eiser's originally.
I think they were based from New Jersey, then Millers store had them when Millers had a huge store in NYC itself..huge multi-level showroom...
I had one of their catalogs at one time...can still picture the blue cover and Eisers printed in gold lettering on a angle across the catalog...early 70's - early 80's can remember seeing/hearing of the saddle brand.
Eiser's has been acquired by several different companies, absorbed into larger entities till their entire tack line in no longer.
Saddles were "Made in England"stamped and all tack of quality leather stock used.
They had spring trees, the safety stirrup bar...
Several different styles of A/P and close contact I remember. I think they also had dressage but not positive of that.
At one time they were the "to have" saddle for many.
The saddles were well made, quality construction that lasted and rode really nice.
If this is what you bought, nice find!! ...
