Clarksdale, MS--the golden buckle on the cotton belt
Tory Leather is also supposed to be US made; and I found a website for a place in Ohio named Tack Unlimited that is made in the USA. Perhaps tack making is now an Amish specialty because they still use horse-power? http://www.tackunlimited.com/horse-c...idles-6772.htm

Got mine from Wayne Rasmussen of The Country Saddler. http://thecountrysaddler.com/legacybridles.html
It's gorgeous. I'm a little ocd about my tack, and BoB / Bartville / Bobby's don't do it for me. I also have a lovely one from KL Select (not red barn!) - pretty sure that's also US made.
A heads up about Quillin: not all of their tack is as nice as their halters (which I love). I got my yoke from them, and it wasn't made in house. I think it's actually Indian leather. They very nicely explained that the cost would be prohibitive if made in house. I don't know anything about their bridles, but would ask the question when ordering. They are great to deal with.
ETA: should have mentioned before that I ended up with my Legacy bridle when I went shopping at a prestigious H/J show. There's definitely good and bad about high level H/J, but you've got to admit that they've got the best tack and clothes.
The Event Bridle, Figure 8 Bridle, and a few others are made by Bartville Harness Shop in Pennsylvania. A lot of their other bridles, like the Ravenna and the Galway, are imported from Asia. Basically if it's not marked "made in the USA" in the description on their web site, you can pretty safely assume that it's imported.
www.zaludsaddlery.com. Martin Zalud can make a bridle for your horse for around the same price (sometimes substantially less than) an off-the-rack model. He's in North Adams, MA. I recommend him for repairs and for unusual bridle requirements, like pony dressage bridles or draft hunt bridles, and the feedback is always positive.
