Artillery Sabre

Blade is 30 in. Weight a little over a pound. Scabbard is solid with no major dings, but rusty. Blade in in great condition. Looks like a 3/4 size 1796 LCS even down to the drag.
Rings and hilt are brass. Blade is solid to the handle, but the guard is a bit loose as the leather washer is missing. Leather is about half gone, but the wood is solid.

Without markings it would be hard to say just when and where (for me, anyway). The blade is a bit different from what you'd expect to see coming out of England. As Hotspur says, the blade looks a bit German (but not Runkel, IMO), and the hilt could be British, American, or German (more likely English or American, though). I'd guess 1805-1830s. You might be able to find a more specific answer at SFI in the Antique & Military section. My knowledge of early 19th century swords is quite slim. These artillery sabers were made in large numbers and came from a variety of sources, so pinning anything down would be hard for me given what I know. Sorry to be so vague!

Well Ive stopped the active rust and cleaned it a bit without removing the patina. Still no marks anywhere. Curses!
Looks better though. Im going to get a chance to get it looked at on the Antiques Roadshow! I won 2 tickets to the show next month in Dallas. BoooYaaaaa!
