I was just looking at some posted photos of a recent fireman's muster. Years ago, I was in a few musters myself. Some of the muster events were with an old hand tub, which is basically a bathtub on wheels and a hand powered pump that an entire crew of firefighters would operate.
Out of curiosity, I looked to see if the old hand tub that I had used to help operate and show is on the internet. I found the firefighter's museum that I actually helped build. I was with the crew that got the hand tub when it was finished being restored.
Here are a few pictures of the hand tub and the museum building.
