Western brands that do larger bridles or mix and match?

I’m looking for a decent quality headstall for my TB/WB mare. Any suggestions for a brand that does at least a 16.5" Browband? Everything I’m finding locally is going to be too small. She’s pretty average length muzzle to poll, but broad through the poll and the cheek.

You might look for mule bridles. They generally have longer browbands and a bit more room for adjustment than horse bridles. For example:

I had one made by Hought for my Warmblood mare. She too needed a wider browband than standard sizing. They did custom sizing at no additional cost - http://www.hought.com/w.lea.tack.html

I had one made by Hought leather. They do custom sizing for no additional charge. http://www.hought.com/w.lea.tack.html
