Simplex 2901-9838 Category : Simplex This horn is designed to go with a Simplex 4903-9101. The grilles on these horns scratch very easily. Luckily, I have some extra grilles, in case the ones on mine get too scratched up. Brand SimplexModel 2901-9838Manufacturer FaradayType Alarm (Horn)

Wheelock CH70-24 Category : WheelockThis is similar in appearance to the Wheelock E70-R, but it is a chime instead of a speaker.
Wheelock STR Category : WheelockThis is from the Exceeder series. It looks like it could be a horn/strobe but is just a remote strobe.
