5 Simplex/IBM 4030s

Feeling a little crazy today, and decided to set off all five of my 4030s. During the testing of each horn, I decided to pick each one up so you could hear how they would sound properly, because I do this test on top of my freezer chest.
In order of appearance:
Simplex 4030-1B (2:27)
Simplex 4031-1 (2:53)
IBM 4030-1 (3:22)
IBM 4030-2 (3:53)
IBM 4030-2B (4:30)
