Western Front Button Down Up Shirt Medium Aztec Rodeo Long Sleeves

Western Front Button Down Up Shirt Medium Aztec Rodeo Long Sleeves I have researched this shirt but I cannot figure out which brand it is. I scanned the QR code that is on the interior of the shirt; and nothing is showing up. The reason I put so much time into researching this item, is because I can feel the quality in the fabric. It has to be a good brand but I cannot confirm what it is. Excellent condition Laying flat Chest: 22" Shoulder to hem: 27"
