1948 Ulra Loud Speaker Is Auto-Truck Size

I don't usually only past part of an article but I haven't been able to find the rest of this one. The mobile truck horn is really cool. If anyone has additional information or pics of this horn please let me know. Perfect size...

Thank you Chris Askew for finding the rest of the article for me.
