Harlin Bros.

  Harlin Bros. Multi-Kord Hawaiian guitars (specifically not steel guitars, according to the company) were manufactured in Indianapolis, Indiana.

  Jay Harlin, one of five brothers, all of whom were involved in the company, was the first person to have a Patent issued for a Hawaiian Guitar, in the late 1930s.
