Paris Gun attacks, the original.

[Trebuchet]

The one in SF is an actual gun. I should not have use the word Model. Several are on display but the SF one if the only one that still works.

OH! That's really cool.

The defences above Davenport in Auckland have a disappearing gun emplacement

There were in position in the San Francisco Bay Coastal Defences as well, same design.
The one currently in San Francisco above Baker Beach is the only one that still works, though. The National Park Sevice ( the SF coastal defence sites are part of the Golden Gate Recreation Area) operates it twice a week.

Who do they fire on?

Who do they fire on?

Guys with guns, of course.

Good page about Fort Casey with lots of pictures of the guns and their mounts.

I've abandoned my plans to attack San Francisco from the sea, just in case they take a shot at me.

So - a triumph for deterrence!

Hoorah!

There's actually a real question there -- how do they get it to go back down? That's done by recoil in an active weapon. Otherwise they're counterweighted to stay up. Perhaps they've fiddled the counterweight to make the operating force very light?

Hope they've got some really good locks on it when they aren't operating it!

The guns have to be cranked down for cleaning and maintenance, so an electric motor would most likely be part of the outfit. Of course if you were on the Top Kick's bad side a manual retraction with a crank might be in the future.

Oakland of course.

BTW, thanks all for the info on the SF Bay batteries I think they'll appear in my forthcoming time travel RPG scenario.

Here's a video of what I assume to be the gun in question being demonstrated. Unfortunately they don't show them getting it back down.

Look around 1:05, you'll see the wheel used to crank it back down. (There should be another one on the other side.)

Yeah, I noticed that. Figured that was probably what it was. If I manage to get to Fort Casey I'll look for the associated mechanism.
