Notice the nose number is 310 in this photo, whereas it is 31 in others. A CDF air attack officer at the Redding Air Attack Base in Northern California, John S. Watt, tells us why: Our original air attack aircraft numbering scheme used two digits. So the primary aircraft out of a base would be "Air Attack 24" and secondary, call-when-needed aircraft would be 121, 122, etc. So now we use a three digit identifier to identify the primary air attack coordinator for conformity, i.e., Air Attack 240, 210, 120, 110 etc. The aircraft in your photos are the same; 31 became 310.
