I believe it is a coal oil lamp that uses different coloured glass lens to signal changes of statis like railway or tunnels

a gas powered streetlamp

Greenhouse heater

It is a soviet army biscuit buttering machine. Called a "Kampechnya' Nudfatna Vechnitatak" (Stlins Whore) by the troops it has been used to make a rough tasting vodka from wood chips or delouse sleeping clothes, depending on the region. No one has ever figured out how to butter biscuits with it. Although it is offically listed as a biscuit buttering machine, no one in the soviet army is exactly sure why.

The CIA spent over 17 million dollars researching its deployment.

It is a kerosene powered railway signal. It has different reflectors to signal whether a train is coming or going, and a couple of knobs at the bottom to control how bright the flame is. Judging by the two screw mounts on the top, I'd say it was meant to hang on a wall, probably at the station itself.

No clue, but dear God do I hope Randall is right lol.
That's so intricate, I hope it's bs, but if it's not, hahahahaha.

olde timey theatrical limelight. calcium carbonate sticks go in the holes. when heated by gas flame, they emit light.

Air Raid Siren

I'll have to say it does look like the sinks from the bathroom in Hogwarts, but I think it really is a sink. Three sinks and mirrors for a public place, such as maybe a locker room.

I've gotta' agree with Gregory - - - it looks like a lighthouse lantern. . .

That's definitely an instrument of torture.

it's a fun fair game, where you have to pee on the propane flames and extinguish them as fast as possible.
The winner has a free meal at the local diner with Emilda the Ouzbek bearded woman.

It's a wall mounted hurricane lamp

It's a kerosene spotlight.

Randall is a genius of some sort (I don't know what sort, exactly, but still). He's the best part of this blog.

That is an air filter for armored vehicle.

It's for checking whether chicken eggs contain chicks, but I think someone beat me to it.

Great guesses, guys! The answer is Egg Candler (guessed right by Bill #14).

I agree with c-dub #35. Randall is definitely a genius and the best part of this blog. I wouldn't dare go head to head with him in a game of Balderdash.
