I would really like to get my hands on 12/10, 12/9 & 12/8 port hand sirens but I think I'd have to get some custom made to achieve that. If I did, I'd use the ACA rotor and stator designs since I like the sound those make. As far as I know the one Adam Smith made many years ago from a Federal Signal 77GA siren with the 9/8 ports is the only dual tone hand siren in existence unless there are others which I've not seen.
