I've looked at a lot of script fonts in the past 40 minutes, and I'm coming to the opinion that this is not a commercial font. There are some poorly drawn letters here, especially the X, P, L and T. Also I seem to notice that the left stroke of the F, H, I and K are nearly identical shapes, and the U, V W and Y all start with a uniform left side. The basic style of the letters I would call a copperplate script (though that may not be the right term), but I can find none of them anywhere with a rounded W like this. This U, V, W, Y looks more like Murray Hill than any copperplate script.

Looking at the lower case letters, I almost thought they were from a German script like Kunstler Schriebschrift, but the k is wrong, among other differences.

I think this may be an amateur attempt to create a font, based on some ideas borrowed from various formal pen scripts, and using copied elements to simplify the creation process.

Where did this sample come from?

It looks like someone attempted to make a "French" version of Künstler. The differences are quite clearly influenced by the French "ronde", particularly the rounded W, the X and the T. It's not a great job, sadly there are no commercial font versions of that handwriting style.

closest i see thus far is Sterling Script. plenty of alternates and swash characters to go with it, so might work out for you. possibly even the basis of your sample?
