Here is a not so great shot of Truck 4, on scene of a fire near Downtown in the early to mid 80s. The ladder assemblies weren't worth anything and developed cracks. They were replaced by the LAFD Shops with Seagrave ladder assemblies.
Originally assigned to the following companies.
60257 1972 Thibault 100' Aerial Ladder Truck (closed cab) builder #457 Truck 26
60258 1972 Thibault 100' Aerial Ladder Truck (closed cab) builder #461 Truck 33
60259 1972 Thibault 100' Aerial Ladder Truck (closed cab) builder #462 Truck 98
60260 1972 Thibault 100' Aerial Ladder Truck (open cab) builder #469 Truck 27
60261 1972 Thibault 100' Aerial Ladder Truck (open cab) builder #470 Truck 93
60262 1972 Thibault 100' Aerial Ladder Truck (open cab) builder #471 Truck 10
Hope that helps.
