Here’s another Sample; This one takes place of a really old 4903-9217 from the year 1994. Again, the horn probably sounds like crap on this unit from age. It’s still amazing regardless! Probably not that loud & very raspy. You can expect that from the 1994 horns honestly. It looked pretty clean from the front but from the sides it has a bit of olive paint from when it was installed & pulled from a working system.
I made a date code that was a little easier to understand such as ‘3994’ rather than the date Code ‘AP’ like it was in the picture. I made a realistic date of Friday, September 30, 1994. I think this is probably a strobe that will make a very loud beep every time the strobe flashes
Here’s a realistic simulation of a Simplex 4903-9219 that was made the exact same day as the 9217 listed up above
