My Uncle Charles was the chauffeur of L37 in da' Bronx when this new FWD Chicago reject was assigned to them. They thought they were getting a new American La France metal aerial ladder like the one at his brother's house at L38. But then this "thing" showed up on Briggs Ave.
Initially it did not even have an hydraulic assist to raise the aerial. My uncle, as the chauffeur, still had to crank the SOB up by himself, just like their old 1930s model.
He was a big, strong WWII Navy vet, typical Irishman truckie of that era. He died of a heart attack in his late '50s. The family always wondered whether this contraption contributed to his demise.
