The fake corriente is just that a fake and a terrible one.
The leather thickness, the way the stirrups are made, the way the cantle is made, the way the pommel is made, the tin that they call silver, everything screams "made in kanpur india"
Those things are 250.00 on ebay and overpriced for what you get..... Get your money back and if need be, sue the person who says it is a corriente if they will not refund your money, the seller as a store will need proof of purchase in a court of law and he will not win. In fact send the pics to coriente, they might want to join in on the lawsuit if this person is saying he is selling corrientes when he clearly is not.
Don't feel bad, you should be able to trust a Store, it is a shame someone would be so deceitful, hopefully it was an honest mistake (their 1st week on the job) and they will cheerfully refund your money.
That being said, your other saddle while not 100% perfect, does fit your Horse better than that fake brand.
May all your Trails be happy and safe ones
