Hi Ken, This is absolutely a piece of Rindskopf ca. 1900. The glass decor is trademark for them, as is the mouth style also being classic Rindskopf. Additionally, the pontil mark (tough to tell for sure from the pic) appears to be a ground, but not highly polished, which is also indicative of their work. Lastly, the shape is also a marker for their production....
They were also partial to making large pieces such as this nice example.
I am attaching two images of other decors in this shape, also with some slight variations to the basic shape.
Hope this helps, Craig
