Focke Wulf, Falcon Wing???

A co-worker has shown me a drawing of a weird Focke Wulf 190 plane
from World War II that has falcon wings. It is called a V19?

What exactly is a V19? I never heard of that before. I know the Jerrys
had V-1 and V-2 rockets, but c'mon a V19?

I thought you fellas would know what the hell this is all about.

My co-worker told me to look it up on the internet and damned if I
can't find squat on it.

Did such a plane exist and why?

Many thanks,

James Dandy
