I had a pair a few years ago and want another. They came in a brown box says Resistol Ranch but I can't find anywhere to shop for them online. 

Does anyone know where I can shop for them? Or better yet, can someone post a link? 

I have some old ones and they were made by Lucchese.  I'm not sure if they still make them or not but you can buy Lucchese and probably get the same fit.
