Aren't those last two Christie pumpers? The Everett F.D. has a horse-drawn one in their collection, and IIRC, that style of steam-powered pumper was made by Christie.
OK, I did a bit of research, and the bottom one is a Christie tractor, designed to pull the pumper, replacing the teams of horses the fire departments used to use.
Glad you remember these. It's before my time. I love seeing the old fire equipment. Almost bought a 1928 Model A fire truck once. Very low mileage which they all are.
This 1948 shot is of a new City of Anchorage Fire Department fire apparatus being loaded into a ship at the Port of Seattle.
