Greetings. Could someone enlighten me regarding the significance of the (apparently) two different types of 20-J 3rd-valve wrap? One type appears to have a double-wrapping near the top, while the other is straight single tubing throughout. Does this have anything to do with the two (?) bore-sizes of these horns, or is it related to the change of production location from Elkhart to TX? Or something? Thank you.
