I have two. One is a Seville in .357 Maximum with a 7.5 inch barrel. The second is a El Dorado in .45 Colt made in Chimney Rock, NC. Both are excellent condition and are possibly my two most favorite handguns. One has a set of initials as a serial number followed by a number. I sure would love to find out who the initials JTB belong to. I probably need to "letter" both guns. It would be nice to know a bit more of their history. I have read everything I could find on the internet, the big puzzle that remains is that serial number.
