Thanks for the added info!
I've received the sword, and will try to remember to take more pictures when I get the chance. Blade shows signs of bluing, and I would not at all be surprised if the blade were French. Türck, it seems, is a location and a surname, so it could be a manufacturer or the name of the owner.
In any case, it actually says Türck on both sides of the blade, with three dots after it on one side. Also, lovely scroll work on the spine!
All in all I'm thrilled,
