On page 52 of Weegee by Weegee, Weegee writes:

“My car became my home. It was a two-seater, with a special extra-large luggage compartment. I kept everything there, an extra camera, cases of flash bulbs, extra loaded holders, a typewriter, fireman’s boots, boxes of cigars, salami, infra-red film for shooting in the dark, uniforms, disguises, a change of underwear, and extra shoes and socks.”

There’s no mention of a complete darkroom…

Coming soon, a complete list of cars (model names, year, color, etc.) owned by Weegee…
