message: the massive Schwerer Gustav 800 mm gun, the largest artillery gun to be fired in anger
I understand that this is to distinguish it from other large artillery that may have only been used for testing or experimental purposes, but that just sounds weird. Perhaps a better wording would be fired in combat? —Preceding unsigned comment added by 75.52.122.167 (talk) 20:01, 2 September 2007 (UTC)

message: Ref the link to the Dahlgren gun. The sign on the Dahlgren gun is somewhat faded but I think I was able to transcribe the exact wording below:
Army 12"/35 Gun
(Model of 1895)
Built at Watervliet Arsenal N.Y. about 1900.
A railway mount (Model of 1918) was built in the Marion Steam Shovel Co., Marion, Ohio 1920.
It's the oldest remaining 12" gun mount on railway and still in firing condition. 
It was used as a primary coast defense weapon through the 1920's. 
In 1942 the Navy acquired it from Aberdeen Proving Ground, MD. 
It was then used for the ballistic test of bombs and various proof and test exercises.

message: I saw a large gun on a railway carriage at a MOD base on Salisbury Plain in 2010 - unable to photograph it or get close to it, and I can't tell you exactly where I saw it, and nobody at the base would talk about it - but it was in the open, not hidden - so perhaps there is another survivor Offbeam (talk) 22:31, 14 March 2012 (UTC)

message: The part about recoil systems isn't really clear to me. What exactly is the difference between the cradle system and the top-carriage system? They both involve the gun mount recoiling on top of a fixed base. Is the difference that the cradle system's mount simply slides, while the top-carriage system mount rolls on small wheels? Doesn't really seem like a fundamental difference to me. And why should the top carriage system be less able to absorb vertical recoil than the cradle system? They both involve the gun mount recoiling along the top of the car chassis. 
The accompanying diagram also isn't totally clear. The text says the top-carriage rolls on wheels, but I can't tell what I'm looking at: is it showing the entire unit, with the mount recoiling on wheels that are so small they can't be included in the image, or is it showing the top carriage alone, and the large wheels are the ones that the mount recoils on? I assume the former, but I couldn't swear on it.
I also wouldn't have understood the description of the sliding recoil system if there hadn't been a photograph alongside to look at. Wouldn't it be more accurate to say the gun was jacked up, rather than saying that the sliders were "jacked down"? Because you're basically jacking the gun up; it doesn't actually leave the ground, but you're taking the weight off of it. The words "Sliding recoil has the car body sitting on a set of wooden crossbeams or "sleepers" placed underneath it which have been jacked down on to a special set of girders incorporated into the track so that about half the weight of the mount has been transferred to them from the trucks" sounds to me like its saying that the crossbeams are something that is fixed to the ground, which the railcar rest upon, like a foundation. By careful reading, you catch that phrase "jacked down onto...girders", which suggests that it's actually saying something else. But I never would have gotten it without the photograph to help out.
