Yes. I agree it is a Model A (Only because I just looked up restored model A engines :-D ) . I wasn't completely sure, but had a suspicion when I saw the little ratcheting gear in the center of the crankshaft on the bottom of the engine. That is what the hand crank attached to. It was designed to 'safely' let the engine turn, once started, without taking the operator for a spin. A short time later, after many broken arms, jaws, skull fractures and broken ribs due to the engine backfiring (The injuries led to death in many cases) <- no kidding .... The electric starter was added along with a 6 volt battery for starting the engine...except in winter when the batteries would die due to extreme cold. Of course, you always had that hand crank, just in case. :-| On a lighter note however, cold engines rarely backfired enough to caused injury. BTW, this history class is over, now.
Of course their showers. :-D Ever seen how dusty a coal miner gets? Even when you hold a piece of charcoal for BBQ'ing your hands get black dust on them. Imagine what you would look like at the end of the day. You would not want to get coal dust anywhere on your car, would you? All other things aside, it was pretty cool that they had showers for them as well as changing rooms.
These are small electric boats. The light blue one still has its battery present at the 'Aft' . That's a fun word for some reason and here is another, TROJAN. The battery is white which was patented by the Trojan Battery Company (No Joke and it's okay to laugh.) There are still a few places that sell this very high quality battery (33% higher price than an AC/Delco battery) for cars and anything else. I had one in one of my cars which was installed by a repair facility and it was quite humorous to see TROJAN in red letters on the white battery when I checked the oil. I knew my car was safe if it ever drove itself to a 'Rave' or some other nightclub so that's something isn't it? :-D
As an Engineer in quite a few disciplines I say it is, in fact, a filtration system. The pipe that rises upwards is a 'Bleed/Overflow' port similar to the air gap on a kitchen sink for the dishwasher. If your drain is clogged, the waste water comes out of the little cap next your faucet on top of the sink. This is an inefficient system that relies on gravity and does not supply a lot of water, by any means. It does make sense as you still would want a system that could operate without electricity, if needed. I could be wrong, and thats fine, but I am pretty confident in my analysis. Apologies if this bored you, thats just what Engineers do for no real reason other than 'It was there.' LOL
It is similar to an alarm system with a battery backup. In case of power failure or high temperature, it would (most likely) page a couple of people about the outage via phone line (Note the bar of screws indicating data lines) so action can be taken. (i.e. Starting a backup generator) If it did not trigger that as well. I don't think it was for warning of Necromancers or rogue morticians. :-D
