I believe this truck is still on display, along with many other classic rigs…at the Hall of Flame Fire Museum in Phoenix, Arizona.

What a nice gem! Even though SEAGRAVE made few changes to the 70th ANNIVERSARY line until it was discontinued in 1970 after 19 years, the later versions had more squared off fenders. So this one was likely early to mid 1950’s vintage.
