Vinyl double hung vinyl window weatherstripping

Not sure of the age of the windows..were there when I bought the house. Some of the weatherstripping is missing along the top edge and is drafty in the winter..I usually just tape the gap between the top and bottom windows for the winter but figured it's time to fix them.

The height of the strip seems closer to 1/4" but may be 3/16 when new. The width of the part that slides into the channel is only about 1/16"...seems odd that it is that narrow but have uploaded a photo.

There is a strip down the middle as well.

Do you sell something similar?

Actually after looking at some of your products, I re-examined the channel that the strip slides into and found the real base is still there. The vinyl is so brittle that the strip snapped off leaving the base behind. I am trying to get a piece out to see how wide it is..but it crumbles when I try to slide it out. Stay tuned! Thanks,
Russ
