San Francisco has three identical Attack Hose Tenders, 7, 13, and 21 on
1974 Ford C-80
00 chassis.  They are powered by Caterpillar 3208
diesel m
otors with body work by Pierce and equipped with Pittman Squrt
54' water towers.  HT-7 is pictured.
At the time, Crown Coach Corp. was the west coast marketing and sales
agent for Pierce Fire Apparatus.  
Crown did not want to tie up production
with commercial chassis rigs at certain times and directed those sales to
Pierce instead.  
These rigs were known for having Crown badges affixed
to them by employees when they arrived in the Crown plant in Los
Angeles for set up prior to delivery.
