I believe it would be OK to post them, but Ellen would probably know for sure.

That 503 is one special engine with it's own unique sound. I remember that our neighborhood GMC "General" firetruck had one and I could tell when it was starting up and leaving the station just by the sound of it, before they got on the siren.
