weatherstripping for Marvin ultimate window

A quick learner from Connecticut says:
I'm looking for window weatherstripping a 2003 install MARVIN DOUBLE HUNG window. I believe the space I'm trying to fill is about a quarter of an inch wide. Attached is a photo of what is there, though I think the shape is distorted. It was probably more of a bubble shape according to the diagram. I've also included some of the original manufacturer diagrams of what the weatherstrip is supposed to look like.
