streamline bean

[Garjan]

Hello

In the extended Spanish Pass the Parcel I found a beautiful bean, but I don't know how to grow it.
It is labelled: Kidney bean, Streamline.
It is quite a large bean, the color of chocolate milk with a black splotch on both sides.

Googling the specifics led me to a runner bean, but the picture didn't show a separate bean, so I'm not sure it's the same one.
Is the label wrong or is there another Streamline? Or is it not a Streamline at all, but another kidney bean?

Does  one of you know more about this bean? Perhaps the PTP-participant who donated the bean?
I'm just curious. And some aspects would help with spacing and timing.
Thanks.
