Help with horns

[robert horman]

I could use help with 6 horns I have. I parted a few 1968-69 B body cars back in the 1990's. I kept some working horns. I want to know which horn in the pictures I posting are from 1968-69 B body cars. Bob Horman

First see what horns are marked HI and what horns are marked LO. It's marked on the casing.
D & E look like candidates.
