The engraving on the pommel-nail-heads say "Gold Cup England". The metal plate under the jockey-flap says "Made in England exclusively for Tack International".
Has anyone ever heard of this maker? I googled "Gold Cup", and all I found was the Beval Gold Cup, which looks identical, but this isn't a Beval. It looks just like the Crump Prix de Saute and the Crosby Prix de Nations.
After I got it cleaned up and conditioned, the leather took to the conditioner right away, and is already very nice and supple. This isn't cheap leather. The leather looks weird in the picture because I'm letting the balm soak in for a day, so I haven't buffed it out yet. The flash also made the color weird. It's actually a deep walnut color, almost black. Everything on it is in mint condition - not a scuff, scratch, or crack anywhere. I'd love to know what this is. Whatever it is, my daughter is sure to enjoy it (we like our saddles flat and skinny)
