Yet more devices that I have not showcased at all, and boy was this one fun!

Love the mechanical horn harmony!

Is there a way to tell these two horn strobes apart just from looking at them? The only difference I see (note I’m an avid enthusiast, not an industry pro) is the flush mount plate. Which I would’ve assumed was only that, a mounting plate.
