Can You Identify These Horns

Pictured are two pairs of horns. I know the ones on the left (pic1) and top (pic2) are “Deluxe Air Horns” for a 1937. They are very rare and I have included them in the picture for reference only. Does anyone have any idea what the ones on the right and bottom are?

TJ, maybe '38, I don't know. They are not '39.
