Wikipedia:Featured picture candidates/Robert Fulton submarine design

 
Original - Cross-section of an 1806 submarine design by Robert Fulton.
 
Unrestored version - Provided for comparison.
Reason
This was a special find: the Library of Congress owns a set of original engineering designs by Robert Fulton, who invented the steamship and was a major innovator of the submarine. So this 1806 schematic doesn't come from a publisher's reprint--it's from Fulton's actual work in pencil, ink, and watercolor--and they made it available in a high resolution scan. Possibly because the file comes from an unusually good source and the original was well preserved, I had the unexpected pleasure of achieving a restoration of higher quality than would normally be possible. Not quite the original Nautilus, but darn close (most of Fulton's designs aren't available online in files that have comparable potential). Restored version of Image:Fultondesign.jpg.

Here's a start: "A = anchor".  :-) Anyone know what L might be? Is that a mine that drops down, or some sort of ballast? Fletcher (talk) 20:19, 11 July 2008 (UTC)[reply]
Oh, I could identify quite a few of these things. Former Navy, and all. But see Wikipedia:No original research. DurovaCharge! 21:59, 11 July 2008 (UTC)[reply]
Meant only in the spirit of curiosity. Fletcher (talk) 22:13, 11 July 2008 (UTC)[reply]
In the spirit of curiosity, C is the anchor line. D-G are a pump to empty the forward water chamber and raise the submarine, and R is the water outlet. I moves the sail. J is a hand crank to move the propeller and P is a lever to change the propeller's angle. I'm not certain what some of the other items are, but H might be an airhole.
