Casement window weatherstripping replacemnt part needed

Struggling to find replacement weatherstripping(WS) for older home windows. Can't ID mfr of window. WS slides into a channel, and is not quite bubble type as is connected to both sides of top edge(~ .25" wide). Length of base extension is ~ .25" ... height of pseudo bubble ~ .3". Perhaps bubble seal could work but key is single vchannel to slide into groove. Think you have something that could work?
