Any Ideas what these Bars go on?

[Buster1]

These came with my '59 Schwinn Jaguar. I'm quite certain that they are not original, but would like to know more before attempting to sell them. Ideas?

Those style of bars are called "SB". I don't know what SB stands for, but that's what they are. My bet is they came off a middleweight Heavy-Duty. Gary
