Red8 it was on the JPSO apco25 system in digital not on the older analog JP system.
Engine 10 fits in with the St Bernard FD numbering system. SBFD station 10 was located at 3901 Bayou Rd pre Katrina. As far as I know no one in JP has an engine 10. JPFD, Kenner, Harahan, and the vol depts use a 3 digit numbering system with the exception of the 2 Gretna departments. I do not believe that either Davy Crockett or Gould have an engine 10 nor do I know of a Bayou Rd in Gretna.
I occasionally go to the NO area and I will look for it again the next time I am there.
